The system below uses a centrifugal pump to circulate water at 19°C, having a vapor pressure of 2320 Pa, from a low reservoir to a higher one through a cast iron pipe with a diameter of 35 cm and surface roughness of 0.25 mm. The minor head losses upstream of the pump are represented by EK1 = 0,6 and downstream by & K2 = 7. After several months of usage, it is noticed that the installation is noisy and consumes...

h A hot water heating system pumps water through a fired heater (furnace) then to a convector to transfer the heat to the room air. (In a real system there would be many convectors in parallel / series, but we have simplified the system to make the details easier to manage.) The piping is 2 inch schedule 40 commercial steel (roughness 0.05 mm) with a total length of 100 m The furnace and the convector can be represented by minor...
