P6.150 Gasoline at 20°C flows at 0.06 m3/s through a 15-cm pipe
and is metered by a 9-cm long-radius flow nozzle (Fig.
6.39a). What is the expected pressure drop across the nozzle?
P6.151 Ethyl alcohol at 20°C flowing in a 6-cm-diameter pipe is
metered through a 3-cm long-radius flow nozzle. If the
measured pressure drop is 45 kPa, what is the estimated
volume flow, in m3/h?
P6.152 Kerosine at 20°C flows at 20 m3/h in an 8-cm-diameter
pipe. The flow is to be metered by an ISA 1932 flow nozzle so that the pressure drop is 7000 Pa. What is the proper
nozzle diameter? Textbook Table of Contents | Study Guide Problems 419
P6.153 Two water tanks, each with base area of 1 ft2, are connected by a 0.5-in-diameter long-radius nozzle as in Fig.
P6.153. If h 1 ft as shown for t 0, estimate the time
for h(t) to drop to 0.25 ft. D = 6 in
d = 3 in h = 1ft
d = 1 in
