Number 3 fuel oil (30 API) is transferred from a storage tank at 60 deg F to a feed tank in a power plant at a rate of 2000 bbl/day. Both tanks are open to the atmosphere and they are connected by a pipeline containing 1200 ft equivalent length of 1.5 inch schedule 40 steel pipe and fittings. The level in the feed tank is 20 ft higher than that in the storage tank, and the transfer pump is 60% efficient.
The Fanning friction factor is given by f = 0.0791/N^1/4 re
a. What horsepower motor is required to drive the pump?
b. If the specific heat of the oil is 0.5 BTU/(lbm deg F) and the pump and transfer line are perfectly insulated, what is the temperature of the oil entering the feed tank?
