A 810kg/m3 density oil is being pumped through a 3-inch St 40 steel pipeline at a velocity of 1.5m/s. The pump work is 250J/kg. a) Is the existing 2kW pump suitable for this task at the factory? What is the daily electricity cost for the pump? The pump efficiency is 80% and the unit price for electricity is assumed to be 3.67TL/kWh. b) The oil tank's liquid level is 2m below the pump and is open to the atmosphere. Considering that the friction losses between the oil tank and the pump are 25J/kg, calculate the required Net Positive Suction Head (NPSH) for the pump. The vapor pressure of the oil is 20.2 kPa. Is a pump with an NPSH value provided by the manufacturer, which is 3m, suitable for this task
