The motor of an electric vehicle runs at an average of 50 hp for one hour and 25 minutes. Determine the total energy. Write the

Sunny_sXe [5.5K]

Answer:

The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.

Explanation:

Power is the rate of change of work in time, since given input is average power, the total energy ( $\Delta E$ ) of the motor of the electric vehicle, measured in joules, is determined by this formula:

$\Delta E = \dot W \cdot \Delta t$

Where:

$\dot W$ - Average power, measured in watts.

$\Delta t$ - Time, measured in seconds.

Now, let convert average power and time into watts and seconds, respectively:

Average Power

$\dot W = (50\,hp)\times \frac{746\,W}{1\,hp}$

$\dot W = 3.730\times 10^{4}\,W$

Time

$\Delta t = (1\,h)\times \frac{3600\,s}{1\,h} + (25\,min)\times \frac{60\,s}{1\,min}$

$\Delta t = 5.100\times 10^{3}\,s$

Then, the total energy is:

$\Delta E = (3.730\times 10^{4}\,W)\cdot (5.100\times 10^{3}\,s)$

$\Delta E = 1.902\times 10^{8}\,J$

The total energy of the motor of the electric vehicle is 1.902 × 10⁸ joules.

A six- lane freeway ( three lanes in each direction) in a scenic area has a measured free- flow speed of 55 mi/ h. The peak- hou

Novosadov [1.4K]

Answer:

0.867

Explanation:

The driver population factor ( $f_{p}$ )can be estimated using the equation below:

$f_{p} = \frac{V}{PHF*N*f_{HV}*v_{p}}$

The value of the heavy vehicle factor ( $f_{HV}$ ) is determined below:

The values of the $E_{T}$ = 2 and $E_{R}$ = 3 are gotten from the tables for the RVs, trucks and buses upgrades for passenger-car equivalents. Therefore:

$f_{HV}$ = 1/[1+0.08(2-1)+0.06(3-1)] = 1/[1+0.08+0.12] = 1/1.2 = 0.833

Furthermore, the vp is taken as 2250 pc/(h*In) from the table of LOS criteria for lane freeway using the 15 minutes flow rate. Therefore:

$f_{p}$ = 3900/[0.8*3*0.833*2250] = 3900/4498.2 = 0.867
