**E-Handout #10
Fluid Flow Meters
ME360 Spring 20**

An engineering laboratory
uses a steam generator to add humidity in a psychometrics
experiment. For
a typical experiment, between 0.250 lb_{m}/min and
0.500 lb_{m}/min
of
water
must be
supplied to the steam generator.

Water is supplied through a 0.250 inch inside diameter pipe,
and passes through a venturi flow meter of throat diameter d
= 0.150 inches. Pressure drop caused by the venturi
restriction is monitored using a water-filled manometer
(Manometer fluid is isolated so that no liquid exchange
occurs between the supply line and the manometer.) What
range of manometer readings bound the typical water flow
rates? (State your result in units of inches of water.)
