Liquid water in a pumped flow system experiences varying pressures as it circulates through the system. One concern in designing any such system is to ensure that cavitation does not occur. If the water temperature during operation of a particular system can vary between 5 deg C and 50 deg C, what would be the minimum permissible absolute pressure that could occur anywhere in the system without cavitations? In solving this problem, you may use the values tabulated in Table A.5 of your text (Fundamentals of Fluid Mechanics) for the vapor pressure of water... or, alternatively, you can use a saturated steam table from your thermodynamics textbook to get more exact temperature-vapor pressure data.
Five kg of water is in a closed rigid container with a volume of 0.3935 m3 and a pressure of 5.0 MPa. Draw and label the states and process on a P-v diagram and determine the amount of heat removed and work done when the pressure is reduced to 1.5 MP..
Water as a saturated vapor at 600 Â°F is contained in a piston-cylinder device that has an initial volume of 30 ft3. The device undergoes a constant temperature process, until the water reaches the saturated liquid condition. Draw and label the state..
Nitrogen in a piston-cylinder assembly undergoes a polytropic expansion process. Initially, nitrogen is at 125 C and 144 kPa. Then it is expanded to a state of 102 kPa and 90 C. determine the heat transfer and work for the process considering no chan..
A slow leak develops in an inner tube (volume, 0.5 ft3, temperature, 600F), wherein it takes 4 hours for the pressure to decrease from 30 to 25 psig. The mass flow rate of air per second under the conditions is given by 0.68pA/(RT)0.5, where the unit..

An insulated piston-cylinder assembly containing a fluid has a stirring device operated externally. The piston is frictionless, and the force holding it against the fluid is due to standard atmospheric pressure and a coil spring. The spring constant ..
A piston cylinder device initially contains 0.15-kg steam at 3.5 MPa, superheated by 5 C. Now the steam loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. the ..
The cold cranking amperes (CCA) of a conventional lead-acid automobile battery is the amount of current the battery can provide at 0°F for 30 seconds and minute in at least 1.2 volts per cell (or 7.2 volts for a standard 12-volt battery). If a batter..
