8.59 Two tanks A and B, of constant cross-sectional
area of 10 m² and 2.5 m², respectively, are
connected by a 5 cm pipe, 100 m long, with
f = 0.03. If the initial difference of water levels
is 3 m, how long will it take for 2.5 m³ of water
to flow from A to B? Considering entry and exit
losses, it can be grossly assumed that the flow
velocity, in m/s, through the pipe is 1.75√h,
where his in m, taking g = 10 m/sec², also, may
take area of pipe as 2 x 10-3 m².
1. Water (Density = 1000 kg/m3) flows downwards through an inclined conical pipe with the following specifications:
Inlet and outlet diameters of the pipe = 0.15m, 0.25 m
Volume flow rate of the fluid through the pipe = 0.0015 m3/s
Pressure at the outlet of the pipe = 2 bar
Height of inlet and outlet above the datum = 2m,1m Perform the following;
(i) Draw the schematic diagram of the system;
(ii) Determine the pressure at the inlet of the pipe.
2.Analyse the effect on the inlet velocity head if the inlet diameter of the pipe is increased for the system given in Question Q3 (b).
Please show your complete solution. Thank you!
Air flows in a steady flow manner through a converging tube. At the inlet the pressure is 690kPaabs and the density is 0.838 kg/cu.m. If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity. Assume that the density is constant.
