In the falling head columns experiment, the time required to drain a tank is given by the equation shown below where D0 is the diameter of the tank, D is the diameter of the outlet, and H is the initial height of the water in the tank. For a tank with a diameter of 5.080 cm, an outlet diameter of 0.635 cm, and an initial water height of 58.30±0.05 cm, determine the time required to drain the tank and the error associated with this calculation.

Suppose that a tank containing a certain liquid has an outlet near the bottom. Let h(t) denote the height of the liquid's surface above the outlet. Torricelli's principle states that the outflow velocity v at the outlet is equal to the velocity of a particle falling freely (with no drag) from the height h (a) Show that v2gh, where g is the acceleration due to gravity. (b) By equating the rate of outflow to the rate of change of liquid...
A 10 cm jet of water issues from a 1 m diameter tank Assume that the velocity in the jet is /2gh m/s where h is the elevation of the water surface above the outlet jet. How long will it take for the water surface in the tank to drop from ho 2 m to h 0.50 m? Problem Definition Situation: Water draining by a 10 cm jet from 1 m diameter tank.

7.24 A pump is used to pressurize air in a tank to 300 kPa abs. e tank has a diameter of 2 m and a height of 4 m. The initial level of water in the tank is 1 m, and the initial pressure at the tank water surface is 0 kPa gage. The atmospheric pressure is 100 kPa. The pump provides a constant head of 50 m. The water is drawn from a reservoir that is 4 m below...

I only want the answer for No 2 Note: The time it takes to get a two-liter bottle empty is given in the picture I only want the answer for No 2 Let h(t) and V(t) be the height and volume of water in a tank at time t. If water drains through a hole with area a at the bottom of the tank, then Torricelli's Law says that dV dt where g is the acceleration due to gravity. So...
1. Atall cylindrical tank, held above ground on stilts, is partially filled with water. (See top figure). The tank has a diameter, D. At time equal to zero, a hole of diameter d is poked in the bottom of the tank, where d<< D. Let z-0 correspond to the bottom of the tank. The initial fluid height is za. Had Use Bernoulli equation to assess the velocity of the fluid as it leaves the bottom of the tank as a...
Consider water being drained from a cylindrical container of diameter D through a hole in the cap, of diameter d, as shown below. Let A be a point on the surface of the water and let B be a point right at the hole. The level of water is h above the hole. If the height of the water level is h = 24 cm, what is the value of vB2−vA2, in SI units? If the diameters are d =...
