Question

4. A circular water pipe having a 5cm inside diameter carries water into the basement of a house at a speed of 2m/s and a pressure of 1.7x10? Pa. (The density of water is 103 kg/m3.) (a) (14 points) On the second floor, 7m above the input point, the water pressure has dropped to 1.0x10? Pa. What is the water's speed on the second floor? (Note: on the second floor, the water pipe has a different diameter – see (b) below.) Answer: (b) (10 points) What is the diameter of the pipe on the second floor?

Step 1

Let's break it down step by step: ### Part (a): Finding the Water's Speed on the Second Floor **Given:** - Initial diameter of the pipe, \( d_1 = 5 \, \text{cm} = 0.05 \, \text{m} \) - Initial speed of water, \( v_1 = 2 \, \text{m/s} \) - Initial pressure, \( Show more…
