Q1 [HW] (a) State two ways in which the entropy of an ideal gas can be increased. (b) What is the change in specific entropy (in kJ/kg.K) for the following fluids from state 1 to state 2? State any assumptions you make. Fluid State 1 State 2 Carbon T = 250 K, P = 700 kPa T2 350 K, P2 = 2,000 kPa dioxide ii Water Water* T = 240 C, saturated liquid T 20 C, P = 200 kPa T2 20 C, P2 = 30 MPa T2 40 C, P2 = 400 kPa *Assume cp is constant and equal to 4.18 kJ/kg.K
