What is the temperature as it leaves the valve assuming
Water flowing in a line at 60 lbf/in2, saturated vapor is taken out through a valve at 14.7 lbf/in2. What is the temperature as it leaves the valve assuming no changes in kinetic energy and no heat transfer?
Expected delivery within 24 Hours
While trapped in a cylinder, 2.27 kg of air is compressed isothermally (with a water jacket being used around the cylinder to maintain constant temperature) from initial conditions of 101 kPa and 16 celsius degree to a final pressure of 793 kPa.
A rod has a cross sectional area of 1 cm^2. Its material has the following strength properties, beyond which it breaks: maximum shear stress,400 kPa; maximum tensile stress, 1.0 MPa; maximum compressive stress, 10.0 MPa.
A flow of 2 kg/s of saturated liquid R-134a at 200 kPa is mixed with 3 kg/s of R-134a at 200 kPa and 10?C. The liquid and vapor phases of the mixture are separated, and each exit separately at 200 kPa.
The inlet state is 60 PSI, 102 F, and the exit state is 14.7 PSI, -20 F, assuming the velocities to be low and the process to be adiabatic, find the required mass flow rate of air through the turbine.
A 1-ft3 tank that is initially evacuated is connected by a valve to an air supply line flowing air at 70oF, 120 psi. The valve is opened, and air flows into the tank until the pressure reaches 90 psi.
Wet steam (P=12.8 kPa, x=0.90 ) enters a heat exchanger with a flow rate of 1.2 kg/s. cold water at 12.8 kPa and K also enters the exchanger with a flow rate of 30 kg/s. the seam and the water mix adiabatically at constant pressure within the heat
