UTAS Property Static Fluid Worksheet
Description
Unformatted Attachment Preview
Determine the total pressure and centre of pressure on a circular plate of diameter 1.5m
which is placed vertically in water in such a way that the top of the plate is 3m below the
free surface of water.
Question 2
Explain why viscosity is the property of the static fluid.
Question 3
If a TANK has one inlet and one outlet, do the mass flow rates have to be equal? Explain.
Question 4
A single tube piezometer installed vertically on a reservoir containing water registers a raise
in its level by 55 cm.
(i) Estimate the pressure in the reservoir.
(ii) What would the piezometer reading be if the reservoir contained an oil of sp.gr. 0.9
for the pressure calculated in case (i)?
Question 5
A horizontal venturimeter with inlet diameter 200 mm and throat diameter 100 mm is used
to measure the flow rate of oil of sp. gravity 0.8. The discharge of oil through venturimeter is
60 liters/s. Find the reading of the oil mercury differential manometer. Assume Cd = 0.98.
