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.arrow_forward(b) A pitot-static probe is use to determine the flow velocity by measuring the differential pressure.

The output of the pressure device is 3.5 V and the linear relationship between the device and the pressure difference is 10 kPa/V. If the measured fluid is water at 20°C, determine the pressure difference inside the system the water velocity. ii) The Pitot-static tube is also commonly use in aircraft.
