FIGURE A-1. Isentropic discharge temperature as a function of suction temper-
ature, k-value, and compression ratio.
RL = P 2 xA H E -P 1 xA C E (A-3)
where RL= rod load in compression in pounds,
A HE = cylinder area at head end in any one cylinder.
A CE = cylinder area at crank end, usually A CF = A HE - rod area.
P 2 = discharge pressure
P, = suction pressure
