1. The problem statement, all variables and given/known data To better fight fires in your seaside community, the local fire brigade has asked you to set up a pump system to draw seawater from the ocean to the top of a steep cliff adjacent to the water where most of the homes are. 1. If the cliff is 12.0 m high, and the pump is capable of producing a gauge pressure of 150 kPa, how much water (in L/s) can be pumped using a hose with a radius of 4.00 cm? A. Iv = 40.4 L/s B. Iv = 45.0 L/s C. Iv = 32.8 L/s D. Iv = 13.6 L/s 2. How would the volume flow rate change if the diameter of the hose were doubled? A. Iv, new = ½ Iv, old B. Iv, new = Iv, old C. Iv, new = 2 Iv, old D. Iv, new = 4 Iv, old (Iv is volume flow rate) 2. Relevant equations 3. The attempt at a solution I know Iv=pi r^2, what else? I also know 2nd question will be equal but just want to make sure.
