There is a storage tank with a height of 5 m. Initially the tank is empty. The cross- sectional area of the tank is 1m?. There is a hole in the storage tank at a level of 2m from the bottom of the tank. The relationship between the volumetric flowrate through the hole and the level of the tank is q=vh. In addition there are two valves at the top and bottom of the tank for inlet and outlet streams. Suddenly, the two valves at the top and bottom of the tank are opened where inlet and outlet stream volumetric flowrates became 1m/s and 0.2m?/s. Determine h(0) and determine if there would be an overflow in the tank

I have a question from my fluid power enginneering class. The question was, standard hydraulic oil is flowing at 10gpm and 10psi at the pump outlet. The system then flows uphill to an elevation of 100ft. What is the pressure at this point?
The water temperature in the tank is 60 °C and the pump has the capacity of 20 ton/hour. Pump is 2m below the bottom of the tank. Diameter of the pipe is 20 cm and the total length of the pipe is 10 m. The pipe is smooth (roughness of the pipe is zero). In the suction line, there are one sharp exit (Kı=0.6), one valve (KL = 17.5) and one 90° elbow (K1=0.3). The required NPSH is given as NPSHrequired=4+3.1050? (V unit in this equation is mº/s).

A uniform cross-sectional water tank is placed in a cart as shown in figure. The cart is mounted on frictionless rollers and the water is discharged to atmosphere through an attached nozzle. However, the the water level the tank is maintained at a constant height h above the nozzle by an external supply at a volumetric flow rate Q. The cart is restrained from moving by the cable seen in figure . The mass of the tank, cart and water is M.
