Question

You have noticed that the shower drain is not draining nearly as quickly as it should be and you wonder how blocked your pipe actually is. You decide the most useful way to measure the clog is by using pressure meters and forcing water through the pipe. You turn on your hose to force water through the pipe and find that the pressure out of your hose after entering the pipe, but before the clog is 4.17x10^5 Pa. You then measure the pressure at the clog at 4.12x10^5 Pa. Just before the clog you determine that water in the pipe is moving at 55 cm/s. The specific gravity of water is 1.0. What percentage of your pipe is blocked by your soap scum and hair?

This is not incomplete this is the question exactly how it was asked.
