A pump delivers water from a tank (A)X water surface elevation-110m) to tank B (water surface elevation= 170m). The suction pipe is 45m long and 35cm in diameter the delivered pipe is 950m long 25cm in diameter. Loss head due to friction hf1 = 5m and h2 3m If the piping are from pipe(1)= steel sheet metal pipe(2)= stainless – steel Calculate the following i) ii) The discharge in the pipeline The power delivered by the pump.

Answer the following: c.) What is the friction factor d.) What is the total coefficient of loss or K. Note that some of the K are provided.
