We use a 5 meter long cable with linear mass density of 9 kg/m to lift a bucket of water with total mass of 15 kg (that is the mass of the bucket and the water). The bucket is leaking water out of a small hole in the bottom at a rate of 3 kg per meter lifted. Find the total amount of work done to lift the bucket 4 meters. Do not include any units in your answer.

A horizontal pipe has a sudden expansion from diameter 8 cm to diameter 16 cm as shown in Figure Q2(b). The velocity and pressure of the water in the inlet of sudden expansion is 10 m/s and 410 kPa respectively. Based on Table 2 and setting given to you, determine the pressure at the outlet of the sudden expansion.

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.

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)

A 1.7 m high by 2.6 m wide by 4.5 m long enclosed tank is filled with water and accelerated horizontally at 5.3 m/s^2. The top of the tank has a small slit across the front. Determine the total force acting on the rear end of the tank in kN.

A hose is connected on one side to a tall tank containing water and theother side is lying on the ground. Once the open side is lying on the groundit has water coming out of it at a speed of 7.4 meters per second. Howmuch do you need to lift the hose to stop water coming out of it?

If you have a flat tire and need to pump up the tire on your car with a hand pump, what force do you have to apply to the pump handle?  Assume the air pressure in your tire will be 20 lb/in2, that is 1.1 KPa (138,0000 N/m2). Let the air pump have a cross-section that is 5 cm in diameter.      It depends on the weight of the car.     About 270 N when the tire is full, not much when you start pumping on the empty tire.     About 270 N for as long as it takes from the beginning.       Just a few newtons until you are satisfied with how full the tire is because of the hand pump.

Q4. Water is flowing in AF pipe (Figure 1) at a velocity of 2 m/s and a pressure of 102400 Pa, the pipe length is 100 m. If the water pressure needs to be at a pressure of 1.6 atm on a lower level. What should be the different in elevation between the upper and lower levels in order to achieve this pressure? Take the density of water 1000 kg/m and gravity is 9.81 m/s, consider the energy loss.

The pump is used to transfer fluid from one location to another of different height. At inlet and outlet atmospheric conditions are present. The pipe diameter increases after the pump outlet. Determine all the surviving terms of energy equation after simplification. FUM kinetic energy, potential energy, pipe losses none pipe losses, potential energy, pressure increase pressure increase, pipe losses, potential energy kinetic energy, pressure increase, pipe losses OOO
