A centrifugal pump is used to pump water from a reservoir whose surface is 4 feet (1.22 meters) above the pump inlet centerline (Z2-0). The piping system from the reservoir to the pump consists of several fittings, with a total minor loss coefficient (K) of 7. a) Estimate the pressure required at the pump inlet (NPSH_Available) at 25°C and 70°C if the required net head (HL, total) at 500 gpm flow rate is 7.5 m. b) According to your findings from part a, at what temperature (25°C or 70°C) can a pump with a required NPSH of 10ft (3.048 meter) be used without cavitation in this system? c) At water temperature 70 C, would NPSHrequired increase or decrease? Why?.

Q.1. A refrigeration process with interstage cooling uses refrigerant HFC-134a, and the outlet of the condenser is to be saturated liquid at 40°C. Refer to the following figure for stream numbers in your solution. The pressure of the flash chamber and the intermediate pressure between compressors is to be 290 kPa. The evaporator is to operate at -20°C and the outlet is to be saturated vapor. The flowrate of stream 1 is 23 kg/h. The flash chamber may be considered adiabatic. The compressors may be considered to be 80% efficient. a) What is the power input required to the first compressor? b) What are the flowrates of streams 6 and 7? What is the enthalpy of stream 4?

An unknown ideal gas at 53 deg F and 3.3 in Hg (gauge) is flowing through an irregular duct. To determine the flow rate of the gas, carbon dioxide, from a modular carbon dioxide tank, is passed into the gas stream. The gas analyzes 1.2% CO2 before and 3.4% after addition. The tank is on a scale and found to lose 12 lb in 10 minutes; What is the flow rate of the ideal gas in ft^3/minute?
Evaporative cooling PLEASE DO NOT USE PSYCHROMETRIC CHART. THANK YOU In the diagram below inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process. Evaporation on the pool resultsin saturated air at the exit. The pool of liquid water is assumed to be at the same temperature as the exitair. Discharge fans at the exit provide a volumetric flow rate of 800,000 ft3/min. In the diagram above inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process.

QUESTION 14 An industrial refrigeratot uses (NH3) Ammonia, and a reciprocating compressor. At the begining of compression the refrigerant is dry staurated at 1bar and operates adibatically with index 1.3 and copression ratio 20. At the final stage, the fluid is saturated vapour. Using the prescribed property table, the specific volume after compression is (to 4 d.p) in (unit symbol). The volumetric ratio is (to 4.d.p) and the final specific volume is (to 2 d.p.).
