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).
A2: FLUID FLOW, FLOW RATE & PRESSURE DROPProblem:4. Determine the average velocity in m/s for water flow in a 2 in diameter pipe, Schedule 40 chlorinated polyvinyl chloride (CPVC) pipe (2.375 in outside diameter and 2.047 in inside diameter) carrying cold water at a volumetric flow rate of 40 gpm.
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.
