A cylindrical tank with a radius of 3ft is filled with water which has a weight density of 62.4 lb/ft^3. The water is to be pumped to a point 2ft above the top of the tank. (a) How much work is performed in pumping all the water from the tank? (B) How much work is performed in pumping 3ft of water from the tank? (C) At what point is 1/2 of the total work done?

Please solve it quickly I am at the exam

Complete Solution please, thanks.   3. A vertical circular stack 30 m high converges uniformly from a diameter of 6 m at the bottom and 4.5 m at the top. Gas with a unit weight of 0.12 N per cubic meter enters the bottom of the tank with a uniform velocity of-assume values with decimals between 3 to 4 m per second- enters the stack. The unit weight increases by 7.5 percent every 2 meters. Find the velocity of flow at every 5 meters along the stack.

The pressure in a water tower is 20,674 Pascals (N/m2) higher than at an open faucet. The density of water is 1000 Kg/m3. Use Bernoulli’s equation to determine the velocity of outflow from the open faucet. If the height difference between the top water level in the tower and the faucet is 7.2 meters, then the velocity of outflow is   ROUND TO 3 DECIMAL PLACES

Water is pumped into a fire hose through a 6 cm diameter pipe with speed 1m/s. The water in the fire hose flows with a pressure of 200000 Pa. At the end of the fire hose is a nozzle (small hole). The pressure decreases to atmospheric pressure (101300 Pa) when the water leaves the nozzle from the hose. There is no change in height moving from the hose to the nozzle. 1. What is the water speed in a 4 cm diameter fire hose? 2. What is the velocity of the water exiting the nozzle (p=1000kg/m³)? 4. What is the diameter of the nozzle? 3. A Fireworker now connects an additional flexible tube to the nozzle (tube and nozzle has same diameter). He lifts the tube to a height of 1 meter above the ground. At what speed does the water come out of the tube? (hint - the pressure at the exit is still atmospheric)

Water flowing in a pipe reaches a point where the cross-sectional area of the pipe is reduced to 1/3 of its previous value. If the speed of the water before the constriction is 1.31 m/s, what is the speed of the water after the constriction?

AT. 2] a water pump is to be used in a water supply system as shown in the figure. The pressure at point 1 is 70 kPaa and the pressure at point 2 is 101 kPaa. The velocity in the 60-mm pipe is 2 m/s. Find the pump power. Neglect friction, and assume no change of internal energy of the water and no heat transfer between point 1 and 2. Take the density of water at standard condition. 2 m2 10 m Pump

A pump has one inlet and two outlets as shown in the figure all at the same elevation. What pump power is required if the pump is 85% efficient. Neglect pipe losses

I need help on this question
