a. Find the work required to pump all the water to the top of the tank.
4.
b.
Find the force due to water pressure on one side of the tank which has the smallest
area.
5. A tank contains 1 kilogram of salt dissolved in 100 liters of water. A salt solution of 0.1 kg
salt/L is pumped into the tank at a rate of 2 L/min and is drained at the same rate. Solve for
the salt concentration at time t. Assume the tank is well mixed.
