A cylindrical tank having a diameter of 3.5m and a height of 10m is full of water. there is an orifice at the bottom of the tank having an area of 0.025 m^2. if the tank has a coefficient of discharge of 0.60, how long will it take to empty the tank in minutes?

Situation 3: A tank with a frustum of a cone having its bases horizontal and axis vertical is 4 m high and is filled with water. It has diameter of 3 m at the top and 1 m at the bottom. The bottom contains orifice whose average coefficient of discharge is C = 0.63 35. What is the size of the orifice that will empty the tank in 7 mins and 20 seconds 100 mm diameter 75 mm diameter 50 mm diameter 125 mm diameter 36. Determine the time to needed to drop the water level to 3 m 255 seconds 120 seconds 350 second 145 seconds 37. Determine the depth of water after one-half of its content is discharge through the orifice. 2.00 m 2.15 m 2.56 m 2.82 m 38. How long it will take to discharge one-half of its initial volume? 260 seconds 244 seconds 200 seconds 168 seconds

A tank in a shape of an inverted cone having a radius of 1 m and a height of 3 m is filled with water. The vertex contains an 100mm diameter orifice whose average discharge coefficient of 0.63. Compute the time needed to empty the tank.
