A conical tank standing 6 m high has a 4 m diameter. A 200 mm diameter orifice is located at its bottom having a meter coefficient of 0.65.

A. Determine the time needed to empty the tank if it was initially full of water.

B. Compute the time needed to drain half of the volume if initially the container was full.

Suppose water is leaking from a tank through a circular hole of area Ah at its bottom. When water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cAh 2gh , where c (0 < c < 1) is an empirical constant. A tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its...

Problem 2 A 30,000 litre water tank has a 4.30 m internal diameter. It has two outlet pipes, one at the base of the tank and one higher up. The distance between the two outlets means that when the water level is at the height of the upper pipe there is still 8,000 litres of water remaining in the tank for fire-fighting if needed. The top portion of the tank is used for stock drinking water. a) If the tank...

An isopentane storage tank has a cylindrical geometry with 2 m in diameter and 4 m in height. The tank is initially found with a liquid level of 0.5 m above the base of the tank. This tank is removed 100 L / s of isopentane as a discharge that is sent to a later process. At a given moment, a recharge of 300 L / s of isopentane is initiated to the tank to recover the level of the...
