Differential equations-Cengel 2.98
A spherical tank of radius R is initially filled with water. Now a hole of radius r is opened at the bottom of the tank and the water is let out. According to Torricelli's law, water comes out of the opening at a velocity v = (2gy) ^ 1/2, where y is the height of the water over the hole at a given moment, and g is the acceleration of gravity. Obtain a relation for the depth of the water with function of time t, and determine how long it takes to empty.
Explain your procedure

Expert Solution

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

Now integrate both sides So, t will go from 0 to t and h will go from 2R to h

So,

t=-((4*H^(3/2)*R)/3 - (16*2^(1/2)*R^(5/2))/15 - (2*H^(5/2))/5)*pi/(Cd*Ah*sqrt(2*g))

Where H is the water at time t in the tank

For H=0, time is

t=((16*2^(1/2)*R^(5/2))/15)*pi/(Cd*Ah*sqrt(2*g))

Kindly revert for any queries

Thanks.

A water tank is spherical in shape with radius of 90 feet. Suppose the tank is filled to a depth of 140 feet with water. Some of the water will be pumped out and, at the end, the depth of the remaining water must be 40 feet. i) Set up a Riemann sum that approximates the volume of the water that is pumped out of the tank. (use horizontal slicing). You have to draw a diagram and choose a coordinate...

A closed, rigid tank is filled with water. Initially, the tank holds 0.6 lb of saturated vapor and 6.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

Problem 3.034 A closed, rigid tank is filled with water. Initially, the tank holds 0.4 lb of saturated vapor and 4.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored. Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu.

5. (Mixing Problem) A very large tank is initially filled with 100 gallons of water containing 5 pounds of salt. Beginning at time t = 0, a brine solution with a concentration of 1 pound of salt per gallon flows into the top of the tank at 3 gallons per second, the mixture is stirred, and the mixture flows out of the bottom of the tank at 2 gallons per second. (a) Letting w = pounds of salt in the...

A hot liquid is filled in a spherical tank with an inner diameter of 3 m and a wall thickness of 3 cm. The tank wall is made of a material with a thermal conductivity of 0.15 W/m∙K. The hot liquid in the tank causes the inner surface temperature to be 100°C, while the tank outer surface is exposed to air at 20°C and has an emissivity of 0.35. Determine the outer surface temperature of the tank. Assume that the...

A non-conducting sphere of radius R centered at O contains a spherical cavity of radius R’ centered at O'. Let d be the displacement of O’relative to 0. Throughout the sphere, there is a uniform charge density rho_0 (except inside the cavity, which is uncharged). (a) Use the principle of superposition to write down an expression for E(r) everywhere. (b) Repeat (a) for the electric potential b(r).

- A cylindrical tank is being filled simultaneously with water and sugar. The input of water and sugar is carefully adjusted so that the concentration of sugar in the water is held constant at 5 grams per cubic meter. The tank has a radius of 5 meters and a height of 10 meters. At a particular point in time, the water level is 3 meters high and rising at a rate of .5 meters per second. At this time, how...

A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when filled. The surface area of the cylindrical part is 2πrh, and its volume is πr2h. The surface area of the hemispherical top is given by 2πr2, and its volume is given by 2πr3/3. The cost to construct the cylindrical part of the tank is $400 per square meter of surface area;...
