Water is coming out of a hole made in the wall of a freshwater tank. If the size of the hole is increased Will the volume of the water coming out per second change?

Consider the diffraction pattern of a small pinhole. As the size of the hole is increased the changes that occur in the pattern

A pump lifts 200L of water per minute through a height of 5m , and ejects it through an orifice 2 cm in diameter. Find the velocity of efflux of water and the power of the pump.

A cylindrical vessel contains a liquid up to a height h. A hole is made on the wall of the vessel. Water comes out through the hole and falls at a distance x from the base of the vessel. At what depth should the hole be created so that x becomes maximum?

A hole of area 1mm^2 opens near the bottom of a large water storage tank and a stream of water shoots from it. If the top of water in the tank is to be kept at 20m above the point of leak, how much water in litres/sec should be added to the reservoir tank to keep this level? (g=10m//s^2)
