Why energy management control system is required in HEV?

Answers

Answer 1

To reduce fuel consumption while maintaining vehicle performance, driver comfort, and component constraints energy management control system is required in HEV.

A supervisory algorithm, also known as an energy management strategy, is necessary for hybrid vehicles to control the different parts of the drivetrain. Usually, when designing an energy management strategy, we face two challenges.

First off, the nonconvex cost function produced by the components' nonlinear behavior makes the employment of optimization techniques more challenging. There are several methods mentioned for dealing with nonconvexity.

Second, it is unknown what the future power and velocity trajectories will be. Using historical or projected vehicle velocity and road grade trajectories to forecast future trajectories could aid in finding a solution that is close to ideal.

What would probably happen if you tried to bake bread without using yeast?Why?

Answers

The thing that will  probably happen if you tried to bake bread without using yeast is that dough may not rise as tall as you're used to because of the lackof the yeast composition in the dough.

What occurs if yeast is absent?

Lemon juice and baking soda mixed in equal parts can be used as a substitute for yeast. So, if a recipe calls for 1 teaspoon of yeast, you can use 1/2 teaspoon each of baking soda and lemon juice. Remember that the dough will start rising immediately, and the bread won't need to prove for the usual amount of time.

You could find that your dough doesn't rise as much as usual and that the flavor and texture are different. However, these alternatives are definitely worth investigating if you run out of yeast, don't have time to wait for bread to rise, or are attempting to eliminate yeast from your diet for health reasons.

Particles q1, q2, and 9 are in a straight line.
Particles q1 = -5.00 • 10-6 C,92 = +2.50 • 10-6 C, and 93 = -2.50 • 10-6 C. Particles qi and q, are separated by 0.500 m. Particles q2 and q3 are separated by 0.250 m. What is the net force on q2?

Answers

Answer:

0.27475 N

Explanation:

To find the net force acting upon q2, we need to find the force exerted by q1 to q2 and the force exerted by q3 to q2, and to do that we should apply the formula

[tex]F = |\frac{kq_{1}q_{2} }{r^{2} }|[/tex]

where in k is coulomb's constant ([tex]8.99*10^9 \frac{Nm^{2}}{C^{2}}[/tex])

q1 and q2 are the charges

and r is the distance between the two charges.

Finding the force exerted to q2 by q1:

[tex]F = |\frac{(8.99*10^{9} * (-5*10^{-6}) * (2.5*10^{-6})}{(0.500)^{2}}|[/tex]

F = 0.4995 N

q1 would be attracted to q2, so it would go to the right, so it's a positive force

Finding the force exerted to q2 by q3:

[tex]F =|\frac{(8.99*10^{9})*(-2.5*10^{-6})*(2.5*10^{6})}{0.250^{2}}|[/tex]

F = 0.22475 N

q3 would be attracted to q2, so it would go to the left, so it's a negative force

F = -0.22475N

Add-up the forces: 0.4995 + (-0.22475) = 0.27475 N

A car accelerates uniformly from rest and

diameter of a tire is 38 cm.
Find the number of revolutions the tire
makes during this motion, assuming no slip-
ping.
Answer in units of rev.

Answers

Answer:

Below

Explanation:

Find distance vehicle travels during this acceleration

d = vo t + 1/2 a t^2    

   a = change in velocity / change in time = 17.9/9.6 = 1.86458 m/s^2

   vo = 0    ( it starts from rest )

then  d = 1/2 ( 1.86458)* 9.6^2 = 85.92  meters

Now divide by the tire circumference to get the number of revs

     85.92 m / ( .38 m * pi )/rev = ~  71.97 revs

Answer: 64.5 rev. ✅

Explanation: The diameter of the tire is 38cm and the car accelerates uniformly from rest to reach a speed of 17.9m/s in 9.6s. The distance covered by the tire can be calculated by using the formula: distance = speed x time.

The distance covered by the tire is 17.9 x 9.6 = 171.84 meters. But when we convert it centimeters it is 17184 cm

The distance covered by the tire is equal to the circumference of the tire, which is equal to 2πd (d is the diameter of the tire). So we can calculate the number of revolutions by dividing the distance covered by the tire by the circumference of the tire.

Number of revolutions = distance covered / Circumference of the tire = 17184/ (2 x π x (38/100)) = 64.5 ✅

The percentage of body weight that is made up of fat when compared to your other tissue, bone and muscles is called body composition.

Body composition refers to the proportion of fat, muscle, bone, and other types of tissue in the body. It is often expressed as a percentage of body weight that is made up of fat. Body composition can be measured using various methods such as skinfold thickness measurements, bioelectrical impedance, and dual-energy x-ray absorptiometry (DXA).

A healthy body composition is generally considered to be one with a low percentage of body fat and a high percentage of muscle mass. It is important to note that body composition is not the same as body weight, as two individuals can weigh the same but have very different body compositions.

If the cue ball stops after the collision, what is the resulting speed of the 8-ball? What is the change in momentum of the cue ball? What is the change in momentum of the 8-ball?

Answers

In accordance with the conservation of momentum law the 8-ball's final speed after a collision is 0.51 m/s.

The momentum, what is it?

momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both direction and magnitude.

Given data :

Mass of cue ball(m1) = 0.17 kg

Mass of 8-ball(m2) = 0.16 kg

Initial speed of cue ball (u1) = 0.48 m/s

Initial speed of 8-ball (u2) = 0 m/s

Final speed of cue ball (v1) = 0 m/s

Final speed of 8-ball (v2) = v2 m/s

The total momentum before and after a collision is equal, according to the conservation law of momentum.

Hence,

m1u1 + m2u2 = m1v1 + m2v2

0.17 × 0.48 + 0.16 × 0 = 0.17 × 0 + 0.16 × v2

0.0816 + 0 = 0 + 0.16v2

The molar conductivity is the conductivity per mole: as the concentration grows, so does the number of charge carriers, and hence the conductivity. The molar conductivity would be constant if the quantity of ions scaled perfectly with the concentration of electrolyte.

However, the conductivity per ion decreases because ions do not act as totally independent charge carriers: they combine, and the rate at which they combine increases as the number of ions increases.

Answers

The total work required to increase the speed of the mass to 11.5 meters per second is 67.5 Joules.

What is speed?

Speed is the rate of motion, velocity, or the rate of change of position in a given period of time. It is a measure of how quickly an object or person moves from one place to another. Speed is usually measured in units such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph). Speed is an important factor in many sports, such as running, cycling, swimming, and racing. It also plays a role in everyday activities such as driving, walking, and getting around. Speed is a key factor in safety, as it can help people stay ahead of potential risks and hazards.

The total work that must be done on the mass is given by the equation W = F x d,
Where W is the work done,
F is the net force applied,
and d is the displacement.

In this case, the displacement is the change in velocity, or 4.5 meters per second.
The force needed to accelerate the mass to 11.5 meters per second is given by the equation F = m x a,
where m is the mass (15 kilograms) and a is the acceleration (4.5 meters per second2).
