Q18:1. A pump steadily delivers water through a hose terminated by a nozzle. The exit of the nozzle has a diameter of 2.5 cm and is located 4 m above the pump inlet pipe, which has a diameter of 5.0 cm. The pressure is equal to 1 bar at both the inlet and outlet, and temperature is constant at 20°C. The magnitude of the power input required by the pump is 8.6 kW, and the acceleration of gravity is g=9.81 m/s². Determine the mass flow rate delivered by the pump, in kg/s. See Answer
Q19:2. A solar collector panel with a surface area of 32 ft² receives energy from the sun at a rate of 150 BTU/hr per ft² of collector surface. Thirty-six percent of the incoming energy is lost to the surroundings. The remainder is used to heat liquid water from 110 to 140°F. The water passes through the solar collector with a negligible pressure drop. Neglecting kinetic and potential energy effects, determine (at steady state) the mass flow rate of water, in lb/min. How many gallons of water at 140°F can eight collectors provide in a 30 minutes? See Answer
Q20:3. The electronic components of a computer consume 0.1 kW of electrical power. To prevent overheating, cooling air is supplied by a 25 W fan mounted at the inlet of the electronics enclosure. At steady state, air enters the fan at 20°C, 1 bar and exits the electronics enclosure at 35°C. There is no significant energy transfer by heat from the outer surface of the enclosure to the surroundings and the effects of kinetic and potential energy can be ignored. Determine the volumetric flow rate of the entering air, in m³/s. See Answer
