A Venturi tube may be used as a fluid flow meter. If the fluid flow rate in m3/s is 1.6 * 10-3 and the radius R1 = 2.4 *10-2 m of the inlet tube is 2.9 times the radius R2 of the outlet tube, and the fluid is water (ρ = 1000 kg/m3), find the pressure difference P1 - P2 in units of kPa. Enter a number with one digit behind the decimal point.

Fluid originally flows through a tube at a rate of 130 cm3/s. To illustrate the sensitivity of flow rate to various factors, calculate the new flow rate (in cm3/s) for the following changes with all other factors remaining the same as in the original conditions. (a) Pressure difference increases by a factor of 1.30. cm3/s (b) A new fluid with 3.00 times greater viscosity is substituted. cm3/s (c) The tube is replaced by one having 4.00 times the length. cm3/s...

An experimental apparatus delivers a viscous fluid through a capillary tube 10 cm long with a bore diameter of 1 mm. The tube is broken, but tubing of bore diameter 2 mm is all that is available. What should be the length of the new tube in cm so that the experiment is otherwise unchanged, i.e., so that the volume flow rate remains as before?

2. Blood with a hematocrit of 45% flows through a 10 micrometer diameter tube. Flow is directly proportional to the pressure difference across the tube and inversely proportional to the apparent viscosity of blood. Compare the actual pressure difference across the tube with the pressure difference necessary to provide the same flow if the apparent viscosity in the tube remained the same as the apparent viscosity in a very large tube. Discuss implications of the Fahraeus-Lindqvist effect on the work...

Chemical Engineering Fluid Mechanics 30. The purpose of a centrifugal pump is to increase the pressure of a liquid in order to move it through a piping system. The pump is driven by a motor, which must provide sufficient power to operate the pump at the desired conditions.
