The figure below depicts a water supply pump drawing from a reservior. Water is withdrawn from the reservoir with water surface elevation of 200-feet (Point #1 in the figure), by a pump whose inlet eye (Point #2 in the figure) is located 6-feet above the water surface elevation. The reservoir water temperature is 80° F, and the pump delivers 2 cubic feet per second of water from a steel inlet pipe 8 inches in diameter. What is the Net Positive Suction Head available for the condition just described. 1
A refrigerator operates according to a Brayton cycle, diagrammed below. The gas conditions (gamma=1.4) at point 1 are P1,V1 and T1=100K.
