Fluid originally flows through a tube at a rate of 110 cm3 /s. To illustrate the sensitivity of flow rate to various factors, calculate the new flow rate for the following changes with all other factors remaining the same as in the original conditions.Randomized VariablesPx = 2.5ηx = 3.2rx = 0.14lx = 4.6Q = 110 cm3/s Part (a) Calculate the new flow rate in cm3/s if the pressure difference increases by a factor of 2.5 . Part (d) Calculate the new flow rate if another tube is used with a radius 0.14 times the original. Part (e) Calculate the new flow rate if yet another tube is substituted with a radius 0.14 times the original and half the length, and the pressure difference is increased by a factor of 2.5.

A particular flow meter allows the volumetric flow rate Q to be calculated from a measured pressure drop Δp. Theory predicts Q ∝ sqrt(Δp), and a calibration provides the following data: Q (m^3/min): 10, 20, 30, 40 Δp (Pa): 1,000 , 4,271 , 8,900 , 16,023 What uncertainty in the measurement of Δp is required to yield an uncertainty of 0.25% in Q over the range of flow rates from 10 to 40 m3/min?

A 100 mm by 50 mm Venturi meter is installed in a 100 mm diameter pipe to measure the flow of a certain liquid (sp gr 1.20). A differential gage connected with the inlet and throat contains a substance (sp gr 1.5) in the lower part of the tube, the remainder of the tube being filled with the certain liquid. The difference in height of substance columns in the two legs of the tube is 75 cm. If the coefficient of the meter is 0.97, compute the actual discharge.
