Apply the first law of thermodynamics to flow system with two inlets and one outlet. Assume that heat is supplied to the system. Draw the neat sketch and lable inlet and outlet properties

An ideal gas passes a diffuser. At the diffuser inlet, the temperature is T1 = 350.00 K, the pressure P1 = 100.00 kPa, the velocity V1 = 200.00 m/s, and the inlet area A1 = 0.30 m2. At the exit, the velocity is very small. The specific heat of the ideal gas at the constant pressure is cp = 1.0050 kJ/(kg·K). The gas constant is R = 0.2870 kPa·m3/(kg·K).  Determine the mass flow rate  __________(kg/s)

A fan manufacturer rates his fans at 152 mm water gage static pressure for 10 m of air per second at 21°C, 1,200 rpm and static efficiency of 69%. At what speed, in RPM, would these fans operate to develop 130 mm water gage when the temperature is 316°C? (14) O 1470 O 1670 O 1770 1870 1570
