BOILER|Pump ExitT, = 40°CP1 = 15.0 MPaBoiler ExitT2 = 550°CP2 = 15.0 MPaThe pump shown in the figure is used to pump 36,000 kg of compressed liquid water per hourinto a boiler. Pump exit conditions are 40 °C and 15.0 MPa. The boiler discharges steam at 550°C and 15.0 MPa (mass flow of steam discharged equals mass flow of water pumped in). Find therate at which heat must be generated by the boiler, Q , in units of MW (1 MW = 1 million Watts).MW

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 enthalpy per unit mass at the inlet, h1__________(kJ/kg)
In the jet impact experiment, water jet impacts on a curved vane in the vertical direction. As shown in the figure below, the exit has an angle with respect to the vertical direction. The distance from the nozzle to the vane surface at the exit is h. The water volume flow rate is measured to be Q, the density of water is p, and the cross section area of the nozzle is A₁. Assume that the flow has reached the steady state. (1) Use the Bernoulli's equation to determine the velocity Vout at the exit of the vane. Assume that friction between water and the curved vane can be neglected. (2) Apply the Reynolds transport theorem to derive the expression of the impact force F, on the curved vane (neglect the jet weight). (3) Under the condition of a fixed volume flow rate Q, determine the maximum impact force Fr,max that can be obtained when the angle varies (e.g. in different vane designs). Va out 9 Ao Vout h
