A 1.5 m diameter vertical cylindrical tank 3m high contains 2.5m of water. A 100mm diameter circular sharp edged orifice is located at its bottom (C=.6). If it will take 98.4 seconds to lower the water level to 1m deep after opening the orifice. How long will it empty the tank?

4. A horizontal boiler drum 6m long and 3m diameter is provided with an orifice 100mm in diameter at its bottom. It contains water up to a height of 2.4m. Calculate the time taken to empty the drum.

A vertical circular tank that is 1.5 m high, has sloping sides. The tank is 50 m and 30 m in the top and bottom diameters respectively. Discharge takes place through a triangular orifice situated at the bottom of the tank. The orifice has a base of 0.8 m long, 0.5 m below its vertex. If the tank is originally full of water, what time is required to empty the tank? Take discharge coefficient as 0.63  Show all formulas and values that are substituted PLEASE

A rectangular tank 6 m long, 3 m wide and 2m deep contains water to a depth of 1 m. It is accelerated horizontally at 2.5 m/s2 in the direction of its length. Determine the maximum pressure intensities at bottom. Unit of the Correct Answer: kPa Group of answer choices 17.31 31.17 13.71 71.13
