1. The problem statement, all variables and given/known data If water flows through a pipe at 0.8m/s , how many litres will flow through the pipe in 1 hour? I think I may be greatly overthinking this question, I keep thinking I need to take into the account of the trench length which is 500m, and the pipe size which is 0.5m diameter. Should I just m^2 * m/s = m*m*m / s = m³/s 2. Relevant equations m^2 * m/s = m*m*m / s = m³/s Pipe diameter: 0.5m Trench length 500m (if relevent) 3. The attempt at a solution I am just assuming the answer is: 0.8 x 60 = 48 48 x 60 = 2880 Therefore the answer is 2880m in an hour. But im not sure how to convert this to litres. Should I use the velocity 0.8m/s and use dimensions? Sorry, such an easy question that has confused me!
