Problem 4 (hand-calculation): Consider the constant-pressure specific heat of air at high temperature presented in ta- ble 4, where T is the temperature and Cp is the specific heat. Determine a least squares quadratic polynomial approximation for this set of data. The quadratic polynomial has the following form: Cp = a + bT+cT. where the coefficients a, b and c are to be determined using the least squares method. Hint Follow the derivation of linear regression discussed in class. You...

Figure P4.95 provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant134a enters the valve atT1=36 degrees C with a mass flow rate of 0.26 kg/s and is throttled to T2 = -8degrees C. The refrigerant then enters the heat exchanger, exiting as saturated vapor with no significant decrease in pressure. In a separate stream, liquid water enters the heat exchanger at T4 = 20 degrees C and exits as a liquid atT5= 10...
