Dvinal [7]

Answer:

a) 6.4 kJ

b) 43.4 kJ

Explanation:

a)

Q_{a} = Heat absorbed = 37 kJ

β  = Coefficient of performance = 5.8

W = Work done

Heat absorbed is given as

Q_{a} = β W

37 = (5.8) W

W = 6.4 kJ

b)

Q  = work per cycle required

Q  = Q_{a} + W

Q  = 37 + 6.4

Q  = 43.4 kJ

The gas tank of a car is filled with a nozzle that discharges gasoline at a constant flow rate. Based on unit considerations of
mojhsa [17]

Answer:

V=\dfrac{dV}{dt}.t

Explanation:

Given that nozzle discharge at constant flow rate.

Volume of tank is V

Lets  constant flow rate =Q

We know that

Q=\dfrac{dV}{dt}\ L^3/s

To find the time t,at a volume V

V = Q .t

V=\dfrac{dV}{dt}.t

Where t is the filling time of volume .

dV/dt is the volume floe rate .

Q is the discharge.
