A particular mixed flow pump is operating just below the point of cavitation. The pump is sited with its intake 3 m above the water level in the reservoir and delivers 0.05 m3/s. The total head at the inlet to the pump is -7 m. (Atmospheric pressure is 101.4 kN/m2 and vapour pressure is 1.82 kN/m2.)
An identical pump is to be installed at a higher reservoir, where the atmospheric pressure is 93.4 kN/m2 and vapour pressure is 1.2 kN/m2. It will be required to operate at the same discharge and head. What is the maximum height the pump can be installed above the water level to ensure cavitation free operation?
Water at 20 degrees flows at a velocity of (V =) 2 m/s in a (D =) 250-mm diameter horizontal ductile iron pipe. Estimate the friction factor f in the pipe, and state whether the pipe is hydraulically smooth or rough.
The outer surface of the tank is cooled by air at 300 K with a heat transfer coefficient of 100 W/m2K. Determine the maximum temperature in the tank. Take the thermal conductivity of the wastes as 2.0 W/mK.
Calculations with steam mixed with additional steam at a different pressure, A steam press at 650Kpa + dryness fraction of 0.9% flows along a pipe at a rate of 3.5Kg per second
10 kPa of pressure required to push a 3 in^2 piston 5 mm into the compacted soil. Compute the CBR (%) if the same 3 in^2 piston required 100 kPa to penetrate 5 mm in calibrated rock soil.
The soil's angle of repose is 35° and its swell is 25%. Find the height and the width of the triangular soil bank that will result from the trench excavation
A tank is divided into two equal chambers by an internal diaphragm. One chamber containes methane at a pressure of 500 bar and a temperature of 20 C, and the other chamber is evacuated.
The packed tower was 30 cm in diameter with sampling ports located at packing depths of 0,2,4,6,8,10, and 12 meters. The loading of water to the tower was 0.039 m^3/(m^2/s), and the temperature of groundwater was 10 degrees celcius.
Assuming D/D/1 queuing, when does the initial queue clear and what are the total delay, the average delay per vehicle, longest queue length (in vehicles), and the wait time of 100th vehicle to arrive (assumin first-in-first-out)
the roller coaster track consists of a circle in a vertical plane of radius 150m. find the magnitude of the total acceleration of the roller coaster if, at the time shown, the car is moving at 50 km/hr and is gaining speed at the rate of 0.4g
The viscosity of a fluid can be measured in an experiment by dropping a small ball into a calibrated tube containing the fluid and observing the random variable X, the time it takes for the ball to drop the measured distance.
On average each student produces 1 kg of carbon dioxide per day. The recommended ventilation rate of fresh air to avoid excessive carbon dioxide buildup is 8 L per second per student.
You have been asked to estimate the optimal size of a small reservoir that is being constructed near Atlanta. Knowing that water is a scarce commodity, you have decided to adopt an "economists" perspective on this problem
