Q2// Determine the enthalpy, the entropy, internal energy and specific volume of steam Vapor at 1100 kPa and x=10%
Air is drawn into the compressor at pressure of 100 kPa and temperature of 22ºC. The volumetricflow rate at the compressor inlet is 0.4 m3/s. The compressor exit pressure is 900 kPa and thecompressor efficiency is 70%. The air leaving the compressor passes through a heat exchangerwhere it is cooled by transferring heat to the atmosphere at 22ºC. The outlet temperature of airafter the heat exchanger is 32ºC. The air passes through a valve and enters a 1 m3 rigid tank. Theinitial pressure and temperature of the air in the tank are 100 kPa and temperature of 22ºC,respectively. The final pressure and temperature of the air in the tank are 900 kPa and temperatureof 90ºC. During the filling process, the tank transfers heat to the surroundings (at 22ºC).Don’t assume constant specific heat.Determinea) The mass flow rate of air entering the compressor, ?̇ (kg/s).b) The rate of power consumed by the compressor, (kW).c) The rate of heat transfer from the heat exchanger to the atmosphere, (kW).d)…
Pure water flows through the cross section of the pipe 0.3m long and 3cm in diameter. The water entering the pipe has a flow rate of 373 K, 0.2 MPa to 2 kg/s. The discharged water also has a flow rate of 2 kg/s. At this time, the temperature is 373 K and the pressure is 0.195 MPa. Under this condition, the density of water is 961.5 kg/cm3. Find what was done at the entrance and exit of the pipe (J/s). Pay attention to the sign.
You are designing a system to mix fuel and air prior to ignition in an engine. Do you want the flow to be laminar or turbulent? Why?
CO2 gas enters the pipe at a flow rate of 2 kg / s, 3 MPa pressure and 500 K temperature. While the CO2 pipe type is flowing, it is cooled down at constant pressure and its temperature drops to 450 K at the pipe outlet. Find the ideal gas using the equation.
Wastewater containing lead is being released from a certain industrial plant. The stream contains X.YZ % Pb and is treated in a unit (maximum capacity = 5000 kg wastewater/hr) that removes 90% of lead in the feed, which is then recycled back into the plant. Another stream from the unit is being released to a lagoon. If the stream leaving the plant has a rate greater than that of the treatment unit. the excess of the capacity of the unit (say, the excess above 5000 kg/hr) bypasses the unit. This excess is combined with the liquid leaving the treatment unit, which is released into the lagoon. The treatment plant releases 7500 kg/hr of wastewater. Let X.YZ be 7.23 Calculate the mass fraction of Pb in the waste lagoon stream. Express your answer in 4 decimal places.
Answer the following questions O of O points Q1* Ql: In a steam power plant, steam enters at 8 MPa and 600 C, the condenser pressure is 8 kPa, and the net power out of the plant is 100MW. Determine 1- The enthalpy at point 1 P2
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.
