Engineering Thermodynamics The general gas equation is (where p = Pressure, v = Volume, m = mass, T = Absolute temperature, and R = Gas constant) pv = RTm pv = mRT pv = (RT)m pvm = C pv = RTm pv = mRT pv = (RT)m pvm = C ANSWER DOWNLOAD EXAMIANS APP
Engineering Thermodynamics The general gas energy equation is (where Q1 - 2 = Heat supplied, dU = Change in internal energy, and W1 - 2 = Work done in heat units) Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU/W1 - 2 Q1 - 2 = dU + W1 - 2 Q1 - 2 = dU - W1 - 2 Q1 - 2 = dU × W1 - 2 Q1 - 2 = dU/W1 - 2 ANSWER DOWNLOAD EXAMIANS APP
