11. Steam at a pressure of 2MPA and temperature 300°C is passed at a constant rate into a desuperheater unit. The desuperheater is accomplished by continuously spraying water at 95 °C onto incoming superheated steam. The amount of water injected is so regulated that both the water and superheated steam finally change into dry steam at 2 MPa. If the resulting mixture of dry saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the mass of superheated steam used per hour and the mass of water to be injected per hour. Fond also the diameter of the pipe through which the superheated steam flows to the superheater if the speed of the steam through the pipe is not to exceed 25m/s.

Question

1.
Steam at a pressure of 2MPA and temperature 300°C is passed at a
constant rate into a desuperheater unit. The desuperheater is accomplished by
continuously spraying water at 95 °C onto incoming superheated steam. The
amount of water injected is so regulated that both the water and superheated
steam finally change into dry steam at 2 MPa. If the resulting mixture of dry
saturated steam leaves the desuperheater at 2MPA and the rate of I kg/s, find the
mass of superheated steam used per hour and the mass of water to be injected per
hour. Fond also the diameter of the pipe through which the superheated steam
flows to the superheater if the speed of the steam through the pipe is not to exceed
25m/s..

Question 3 Consider the turbocharger of an internal combustion engine. The exhaust gases enter the turbine at 450°C at a rate of 0.02 kg/s and leave at 400°C. Air enters the compressor at70°C and 95 kPa at a rate of 0.018 kg/s and leaves at 135 kPa. The mechanical efficiency between the turbine and the compressor is 95 percent (5 percent of turbine work is lost duringits transmission to the compressor). Using air properties for the exhaust gases, determine:(a).The turbine power output, compressor power input, air temperature at the compressor exit,(b).The air temperature at the compressor for the case of isentropic process and isentropic efficiency of the compressor.
CO2 is needed in a surgical suite for abdominal laparoscopic surgery. You have already designed a nozzle to step down the pressure from the gas cylinder to the delivery hose. The well-insulated delivery hose has a 2.2 mm inner diameter. The inlet conditions to the delivery hose are 103 psia and 17°C. Typically, the surgeon uses 4 to 6 L/min of gas at pressures between 10 to 20 mm Hg to inflate the peritoneal cavity; however, the delivery system must be able to provide flow rate of 17.5 L/min at 20.0 mm Hg for safety. The surgeon will use a pin valve to control the flow rate and maintain the operating space. The gas temperature should not be any colder than 10°C when delivered to patient, or tissue damage might occur. Determine the acceptable delivery hose length to meet the surgical criteria. State assumptions.
