A pump having the characteristics given( N=2133.5 rpm, n=35.6 rps, D=37.1 cm) pumps water at 25 degree C from a reservoir at an elevation of 366 m to a reservoir at an elevation of 450 m through a 36 cm steel pipe. If the pipe is 610 m long, what will be the discharge through the pipe?
(1) To provide $750000 for th construction and $250000 for the initial equipment of a small engineering laboratory ; (2) to pay the $150000 per year laboratory operating cost; and (3) to pay for $100000 of replacement equipment every 4 years, beginn..
A reservoir discharges into a long trapezoidal channel with a bottom width of 20 feet, 3 to 1 side slopes, a bottom slope 0.001 and a roughness coefficient of 0.025 the reservoir surface is 10 feet above the invert at the channel entrance
A small house is built in the arctic. It has four square walls of 500 ft2 each. For simplicity, we will assume it has no windows, and we are only interested in calculation the heat loss through the four walls. A total of one hundred Watts (100 kW)..
plane gate of uniform thickness holds back a depth of water. Find the minimum weight need to keep the gate closed. theta=30degrees L = 3m w = 2m
The plant will be designed with a rapid mix unit followed by flocculation and sedimentation basin. The water source has an average winter water temperature of 40 and an average summer water temperature of 70oF.
Two identical pool balls of 57.15 mm diameter may move freely on a pool table. Ball B is at rest and ball A has an initial velocity v=v0i. (a) knowing that b=50 mm and e=0.7, determine the velocity of each ball after impact.
The channel has side slopes of 4H:1V and a longitudinal slope of 0.5%. Assume a depth of flow of 6-inches. The parking lot slopes at 1% toward the channel from both sides, and the 2-year, 24-hour rainfall is 2in.
Complete mixed system that contains a single reactor against a system that contains three Complete Mixed reactors of equal volume in series. (total volume of three reactors should be equal to the single reactor)
The surface area of clay particles can be determined by measuring the number of adsorbate molecules it takes to form a monolayer. The adsorbate molecules used for these measurements are usually N2 gas, therefore partial pressure "P" is used instea..
The saturated unit weight (sat) of the sand is 20.0 kN/m3 and the anticipated depth to water in the well during pumping is 20 m below ground surface.
A gas is compressed at a constant pressure of 0.800 atm from 9.00L tp 2.00L. in the process, 400J of energy leave the gas by heat. (a) What is the work done on the gas? (b) What is the change in it internal energy?
The dry weight of a core is 28.20 gm. When saturated with a brine having a density of 1.15 gm/cc, the weight increases to 31.50 gm. Calculate the apparent porosities if the matrix is 1) quartz or 2) calcite.
