During a drought, the water level in a dam fell 3 inches per week for 6 consecutive weeks. What was the change in the water level in the dam at the end of this period?

During the summer, the level of water in a pond decreases by 2 inches every week due to evaporation. What is the change in the level of water over a period of 6 weeks?

A water tank is constructed on the top of a building. With what speed will the water come out of a tap 6.0 m below the water level in the tank? Assume steady flow and that the pressure above the water level is equal to the atmospheric pressure

A aluminum can of cylindrical shape contains 500cm^3 of water. The area of the inner cross section of the can is 125cm^2 . All measurements refer to 10^@C . Find the rise in the water level if the temperature increases to 80^@C . The coefficient of linear expansion of aluminum =23 xx 10^(-6)C^(-1) and the average coefficient of volume expansion of water= 3.2xx10^(-4)C^(-1) respectively.

The lower end of a capillary tube is immersed in mercury. The level of mercury in the tube is found to be 2 cm below the outer level. If the same tube is immersed in water, up to what height will the water rise in the capillary ?

A motor boat heads upstream a distance of 24 km in a river whose current is running at 3 km per hour. The trip up and back takes 6 hours. Assuming that the motor boat maintained a constant speed, what was its speed in still water?
