1. A transition in a pipeline is connected by a
differential manometer. If the manometer reads
12 in. of mercury, what is the discharge through
the transition?
2. A natural gas, for which k = 1.33 and R = 96.6
ft-lb/lb-oR, flows through a venturi-meter with
pipe and throat diameters of 10 and 4 in.
respectively. The initial pressure of the gas
is 130 psia and its temperature is 60oF. If the
meter coefficient is 0.98, find the rate of flow
in GPM for a throat pressure of 100 psia.
