4.1 A centrifugal pump is used to pump water from one tank to another. The difference in height between these tanks is 140m. What is the theoretical minimum power required to pump 15,000kg of water from the bottom tank to the top tank in 6 hours? Assume that gravity = 10m/s2. Show your calculations in your answer. Start writing here: 4.2 In reality, there is friction in the piping, which means that an additional pressure equivalent to a height of 100 m is needed to pump the water from the bottom tank to the top tank. What is the minimum power required when accounting for friction? By what percentage has friction increased the minimum power required? Remember to show your calculations. Start writing here
