In a produce chilling system, air is cooled by being passed over a heat exchanger coil througlh which R-134a flows steadily at a rate of 15 lbm/min. Prior to entering the heat exchanger coil, the refrigerant passes through a throttling valve as shown in the figure below. The R-134a enters the valve as a saturated liquid...

3. Shown is the hydraulic circuit of a load-lifting hydraulic system. The lowering speed is controlled by means of a throttle-check valve. Discuss the construction and operation of this system. Redraw the hydraulic circuit in the load-lowering mode, then calculate the pressure in the cylinder rod side, P the inlet flow rate, Qu outlet...

-Rome can get pretty hot in the mid-summer! Most of the air conditioning units in the Tiber campus use the working fluid R-134a (1,1,1,2-tetrafluoroethane), which is replaces the less environmentally-friendly R-12 of years ago. a) Illustrate the following air conditioning cycle, indicating material, heat, and work flows, as well as given/known temperatures and pressures: R-134a is pressurized to 10.2 bar...
Figure P4.96 provides steady-state data for a throttling valve in series with a heat exchanger
4.96 Figure P4.96 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 2 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10℃ with no significant decrease in pressure. In a separate stream,...

#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,...

A throttling calorimeter shown below is used to determine the quality of a two-phase mixture of R-134a refrigerant that is flowing in a tube. The calorimeter operates by bleeding offa small fraction of the flow stream and throttling it to a lower pressure. The device is based upon the fact that over a wide range of temperatures and qualities, the...
