Problem on First Law of Thermodynamics
#firstlawofthermodynamics #piston #cylinder #heattransfer #workdone #internalenergy #cycle A piston and cylinder machine contains a fluid system that passes through a cycle of four processes. During a cycle, the sum of all heat transfers is -170 kJ. The system completes 100 cycles per minute. Complete the following table showing the method for each item and compute the net rate of work output in kW.
Process Q (kJ/min) W (kJ/min) ∆E (kJ/min)
a - b 0 2170 ---
b-c 21000 0 ---
c-d 2100 -- -36600
d-a --- --- ---
