Answer:
Heat supply rate is measured at 8.901 horsepower.
Explanation:
Energy efficiency of the electric vehicle, as per Thermodynamics (
), is the proportion of translational mechanical power (
), expressed in horsepower, and electrical energy (
), also in horsepower. The heat supply rate (
), indicated in horsepower, that the motor delivers to the engine bay under full load can be determined by subtracting the translational mechanical energy from the electric energy. This is expressed as:
(1)
(2)
(3)
If we have the values of 
and 
, the heat supply rate can be calculated as:
The heat supply rate amounts to 8.901 horsepower.
Answer:
Explanation:
In a steady-state condition, the total volume exiting matches the total volume entering, and
the total amount of salt entering equals the total amount of salt exiting.
The volume entering each minute is = 2000 + 2 x 10³ x 60
= 122000 L.
The total salt entering per minute = 1200 x 2000 + 20 x 2 x 10³ x 60
= 2400000 + 2400000 mg
= 4800000 mg.
The volume of water exiting each minute = 122000 L.
The total salt exiting each minute = 4800000 mg.
The concentration of salt in the exiting water = 4800000 / 122000
= 39.344 mg / L.
Explanation:
At a temperature of 
and relative humidity of 86%, the humidity ratio stands at 0.0223 with a specific volume of 14.289.
At a temperature of and relative humidity of 40%, the humidity ratio is 0.0066 while the specific volume is 13.535.
To determine the mass of air, the following formula can be used:
Now, we will calculate the volume
The duration required to fill the cistern can be determined with the equation:
By substituting the values into the preceding formula, we find:
Thus, the hours necessary to fill the cistern amount to 4.65 hours.
