An Olympic swimming pool is roughly 72 m long and 39 m wide. How
long will it take to fill such a pool with an ordinary garden
hose?
Hint:
You need to make a reasonable estimate for the depth of the pool
and explain how you came up with an estimate. Estimate the flow
rate for the garden hose in the same way. Do the necessary
calculations and explain your result.

A swimming pool is 50 m long and 20 m wide. Its depth decreases linearly along the length from 9 m to 1 m. It is initially empty and is tilled at a rate of 1 m^3/min. How fast is the water level rising 810 min after the filling begins? How long will it take to fill the pool? The water is rising at a rate of m/min 810 min after the filling begins. (Simplify your answer.)

(c10p4) A swimming pool is 50 m long by 23 m wide and is less deep at one end than at the other. The depth at the shallow end is 1.02 m, and the depth at the deep end is 4.65 m. The slope is continuous (smooth) from one end to the other. What is the difference in pressure on the bottom at opposite ends of the pool?(expressed in Pa)

Motivation. Why is estimation useful? If we numerically compute the value of a certain quantity using some potentially complicated methods, at the end when we get a result, we can perform a rough check on our result by estimating what the result should be, and comparing this estimate to our computed result. Similarly, if someone makes an assertion to you about the numerical value of some quantity, you can perform a quick, rough check of that assertion through estimation. In other words,...
