Answer:
Input power = 2200 w
Output power = 1899.7 w
Cost = $ 4.752
Step-by-step explanation:
Assuming a Direct Current scenario, electric input power is calculated by:

Where
Pi is Power in watts (w)
V is voltage in volts (v)
I is current in amperes (a)

Then, the formula for output power is

Where
Po is Power in watts (w)
T is torque in NM (v)
S is speed in RPM (rpm)
9.5488 is used to convert rpm unit to rad/sec unit

Finally, to calculate the cost of operation, we simply multiply the input power, total hours of operation and value per hour:

Where
CO is cost of operation in $
Pi is Power in watts (w)
H is operation time in hours (hs)
C is value per kw per hour (kwh)
1000 is used to convert watts unit to kilowatts unit
