Answer the following questions about air flowing through a nozzle as shown in the schematic below. The air enters the nozzle at 2.2 kg/m³ and 34 m/s and leaves at 0.72 kg/m³ and 130 m/s. The nozzle inlet area is 60 cm². The mass flow rate is 4.5 kg/s. The outlet cross-sectional area is 1 cm². P1 Nozzle V₂ P2
A steam turbine operates with 1.6 MPa and 350 deg C steam at its inlet and saturated vapor at 30 deg C at its exit. The mass flow rate of the steam is 22 kg/s, and 610.2 kW of heat is lost through the casing of the turbine. 1. Create a sketch of the problem and indicate the control volume. 2. Write the continuity and energy equations and cross out terms by stating the relevant steady state assumptions. 3. Determine power produced. 4. Determine the specific work.
A purifying air cooler is composed of electronic air filter and a water cooling system. The air passing through the filter is cooled by the water flowing through the cooling pipe located inside the system. Water enters the pipe with a speed of 0.92 m/s at a temperature of 18 C. The water then exits the pipe at 30 C. In the current environment, the purifying air cooler is able to absorb heat from the atmosphere at the rate of 1.654 kW while simultaneously cooling the electronic components inside the device which produces heat at a rate of 0.845 kW. Determine the internal circumference of the pipe to be used for the purifying air cooler. *be careful when selecting the system boundary Answer in meters
The inlet temperature of an air compressor is T₁=300°K and the outlet temperature is T2-500°K. The compressor operates at a mass flow rate of 0.093kg/sec and the heat lost during the compression is 10kJ/kg. Assume that the air is an ideal gas with Cp=1.004 kJ/(kg°K). Calculate the mechanical power needed to be provided to the compressor shaft. Present your answer in kilo- Watts (kJ/sec).
The kinetic energy of air as it flows through an adiabatic nozzle. decreases increases remains constant
