1. A liquid flows from A to B in a horizontal pipe line shown at a rate of 3 ft³/s with a friction loss of 0.45 ft of flowing fluid. For a pressure head at B of 24 in., what will be the pressure head at A?

2. Water flows through the pipe contraction shown at a rate of 1 ft³/s. Calculate the differential manometer reading in inches of mercury, assuming no energy loss in the flow. Be sure to give the correct direction of the manometer reading.
