Thermodynamics: Valve and Heat Exchange 4.95
Figure P4.95 provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant134a enters the valve atT1=36 degrees C with a mass flow rate of 0.26 kg/s and is throttled to T2 = -8degrees C. The refrigerant then enters the heat exchanger, exiting as saturated vapor with no significant decrease in pressure. In a separate stream, liquid water enters the heat exchanger at T4 = 20 degrees C and exits as a liquid atT5= 10...

#4. To operate a steam turbine in part-load output, a throttling valve is used as shown. The valve reduces the pressure of steam before it enters the turbine. The state of steam in the supply line remains fixed at 2 MPa, 500°C and the turbine exhaust pressure remains fixed at 10 kPa. Assuming the turbine to be adiabatic and reversible, determine (a)the full load specific work output in kJ/kg, (b)the pressure of the steam must be throttled to for 75%...

One part of the tank contains 2.5 kg of compressed water at 400 kPa and 60°C while the other part is evacuated. The partition is now removed, and the water expands to fill the entire tank, Determine: d) The entropy change of water during this process, if the final pressure in the tank is 40 kPa....

LLLS Moran, Shapiro, Boettner, Bailey, Fundamentals of Engineering Thermodynamics, 9e Help I n Assignment NEXT URCES Problem 4.067 S The figure below provides steady-state data for a throttling valve in series with a heat exchanger. Saturated liquid Refrigerant 134a enters the valve at a pressure of 9 bar and is throttled to a pressure of p2-3 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10°C with no significant decrease in pressure. In a separate stream,...

Saturated liquid water at 10.0 MPa is throttled through a partially open valve (isenthalpic process) and discharged into a tank at a pressure 0.1 MPa adiabatically, aergonically, and without any change in its kinetic or potential energy. (NOTE: When the pressure on saturated liquid water is suddenly reduced in an adiabatic aergonic, steady flow process, part of the initial liquid is very quickly converted into a saturated vapor at the lower pressure, with the vaporization energy (heat of vaporization) coming...

Consider 0.8 kg of N2 at 300 K, 1 bar contained in a rigid tank connected by a valve to another rigid tank holding 0.3 kg of CO2 at 300 K, 1 bar. The valve is opened and gases are allowed to mix, achieving an equilibrium state at 280 K. Determine: (a) the volume of each tank, in m3. (Correct .7124 m^3 and .17 m^3) (b) the final pressure, in bar. (Correct 0.9331 bar) (c) the magnitude of the heat...
