A fire truck has its hose connected to a hydrant where the pressure is 7x10^4 Pa gage. The hose then connects up to a pump run by the engine of the fire truck. From here there extends hose to a fire fighter who, while crouching, is aiming the water at a 60 degree angle with the ground to enter a window on the third floor 13 m above the nozzle at the end of the hose. As the water goes through the window, it is moving parallel to the ground. The total length of the hose is 65 m with 200-mm diameter. The exit diameter of the nozzle is 100 mm. Take e/D for the hose as 0.0001. What power is needed from the pump on the water? Take the nozzle exit to have the same elevation as the hydrant outlet. Neglect minor losses. Take the kinematic velocity to be 0.113x10^-5 m^2/s.
A pipeline 1200 ft long and 8 in. in diameter has at its inlet point 75ft of available hydraulic energy with respect to the reference level. The velocity in the pipe is 5 fps: the pressure at its end is 12psi.
An underground storage vault is to be constructed to serve as a detention pond for a heavily urbanized area. The walls of the vault will be vertical, but the flow will be sloped along its length to promote drainage.
two particles start from the same point along the same straight line and at the same instant. the first particle

an incident occurs on a freeway that has a capacity in the northbound direction, before the incident, of 4000 veh/h and a constant flow of 2900 veh/h during the morning commute.
AGNO3 is added to a solution containing 0.001 mol Cl- amd 0.001 mol Br- per liter. What are the concentrations of Cl- and Br- remaining when AgCl just begins to precipitate?
A new section of richmod highway is being designed as a six-lane facility (three in each direction) with a two-way, left-turn lane. Determine the peak hour LOS.
A sample of soil is compacted into a 9.44x10-4 m3 laboratory mould. The mass of the compacted soil specimen is 1.91 kg and its water content is 14.5%. Using a specific gravity of solids of 2.66, compute the degree of saturation, density and unit weig..
An experiment was conducted to determine the hydraulic conductivity of an artesian aquifer. The piezometric heads at two points 150m apart were found to be 55 m and 48.5 m above a datum.
