A cylindrical water tank has a radius of 2.8 feet and a height of 5.6 feet
Homework Answers
Given that water is pumped out at a rate of 36 cubic feet per minute.
So, we have to find the volume of the cylindrical tank
We know that volume of the cylinder is given as V = πr2h
where V is volume, r is the radius and his height of the cylinder
Given that
r = 2.8 feet and h = 5.6 feet
Therefore,
Volume, V = π × 2.82 × 5.6
V = 137.93 cubic feet
Pumped out rate = 36 cubic feet per minute
Therefore, time is taken to empty the water tank
t = volume/rate
t = 137.93/36 min
t = 3.83 minutes
Hence, as per the given option, time = 4 minutes
Answer:
C. 4 minutes

A cylindrical tank is being filled with water. The tank is initially empty but then water begins to flow into it at a rate of 62.00 kg/min. There is a small hole of radius r = 0.7000 cm at the bottom of the tank where water can escape. Because the flow rate of water leaving the hole is initially at a slower rate than water entering the tank, the water level rises. The average velocity of water leaving through the...

Water is leaking out of an inverted conical tank at a rate of 11700 cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height 8 meters and the diameter at the top is 6 meters. If the water level is rising at a rate of 26 centimeters per minute when the height of the water is 5 meters, find the rate at which water is being...
