sive Problems C6.1 A pitot-static probe will be used to measure the velocity distribution in a water tunnel at 20°C. The two pressure lines from the probe will be connected to a U-tube manometer that uses a liquid of specific gravity 1.7. The maximum velocity expected in the water tunnel is 2.3 m/s. Your job is to select an appropriate U-tube from a manufacturer that supplies manometers of heights 8, 12, 16, 24, and 36 in. The cost increases significantly with manometer height. Which of these should you purchase?
The compressor of a refrigeration unit operates with a flow rate of 1800 kg/hr and an isentropic efficiency of 0.75. The working fluid is R-134 which enters as a saturated vapor at 20 C and exits the compressor at a pressure of 1 MPa. Determine the p..
