Water flows from a ground storage tank that is 450 feet above a town's water distribution system. The pressure at the entrance of the system must be at least 75 psi and the demand is 1350 GPM. The pipe material is to be riveted steel and the length of pipe is 5,000 feet. What size pipe should be used?
Given that the gate is 3 m wide and will just start to open when water height reaches 6 m, determine the weight of the gate.
The Earth may be considered as a sphere whose diameter is 8000 mi. and whose density is roughly approximated to be 6560 kg/m^3. What is the mass of the Earth in pound-mass and kilograms
At a temperature of 9°C, a 2-mm gap exists between two polymer bars and a rigid support. Bars (1) and (2) have coefficients of thermal expansion of t1 = 102 x 10-6 /°C and t2 = 66 x 10-6/°C, respectively.
