Oil has been flowing from a large tank on a hill to a tanker at the wharf. The compartment in the tanker is nearly full and an operator is in the process of stopping the flow. A valve on the wharf is closed at a rate such that 1 MPa is maintained in the line immediately upstream of the valve. Assume: Length of line from tank to valve 3 km Inside diameter of line 200 mm Elevation of oil surface in tank 60 m Elevation of valve on wharf 6 m Instantaneous flow rate 2.5 m 3 /min Head loss in line (exclusive of valve being closed) at this rate of flow 23 m of oil Specific gravity of oil 0.88 Calculate the initial instantaneous rate of change of volume flow rate.

Water (@ 45°C) is flowing in a horizontal pipe with an increasing cross-sectional area. The measured pressure drop in the piper is 4.1 psia. If the cross-sectional area at the exit of the pipe is 2x the cross-sectional area at the entrance, what is the V of the water as it enters the pipe? Assume that frictional losses are negligible .
A circular cone-shaped container is filled with water at a level h0. At time t=0 a faucet is turned on and starts filling the cone with water at a constant flow rate Q. (a) Determine the expression for the variation of the level of water with time in terms of the initial level and volume (h0, V0) and the feed flow rate Q. (b) At what time will the water start to spill over if the cone was initially filled to 1/3 of the cone's total height? Determine a numerical value for the time in the case where the cone angle is 45o, h0=20cm and Q=2l/s.
Water from an open tank elevated 5m above ground is allowed to flow down to a pump. From the pump, it then flows horizontally through 100m of piping, and out into the atmosphere. If there are 2 standard elbows and one wide open gate valve in the discharge line, determine a) all friction losses in the system and b) the power requirement of the pump if it is to maintain 0.8 cubic meters per minute of flow. Assume a pump efficiency of 55%, and that friction is negligible in the pump suction line.
