Water is flowing in a fire hose with a velocity of 1 m/s and pressure of 2.8 bar. At the nozzle the pressure decreases to atmospheric pressure 1 bar, there is no change in height. Calculate the velocity of the water exiting the nozzle. (Hint: The density of water is 1000 kg/m³ and gravity g is 9.8 m/s²). the velocity at the nozzle in m/s

a spherical tank 4 m in diameter is 3/4 full of water. find the work required in pumping all the contents when the pump is placed on the top of the tank.

Water is flowing in a fire hose with a velocity of 1.0 m/s and a pressure of 200 KPa. At the nozzle the pressure decreases to atmospheric pressure (101.3 KPa), there is no change in height. Use the Bernoulli equation to calculate the velocity of the water exiting the nozzle. Draw diagram neatly.

The velocity of water in ft/s at the point of discharge is given by v = 12.88 P, where P is the pressure in lb/in.2 of the water at the point of discharge. Find the rate of change of the velocity with respect to pressure if the pressure is 10.00 lb/in.2.

A pump is supplying water at the rate of 4ft^3/s it lifts water to a height of 15ft. Determinte the power that the water is being delivered to by the pump  (hp). If the pump has 80% efficiency , find the power that needs to be supplied to the pump (hp)

Water is being pumped from an atmospheric source on the ground at the rate of 200 liter/minute to a pressurized tank on top of an office building through a constant diameter pipe.  The discharge to the pressurized tank is 20 meters off the ground and the tank has a gauge pressure of 5 bar.  Ignoring frictional losses, determine the    a)power the pump must supply the fluid in W (Correct Answer is 2321 W)   By performing an energy balance around the pump and ignoring friction and any changes in height between the inlet and outlet of the pump determine the:   b) increase in pressure across the pump in psi (Correct Answer is 101 psi)

Water with a mass rate of "M" continuously enters a tank with a diameter of "D". If a hole in the bottom of this tank allows water to escape, find the maximum height of the tank.
