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.
(b) A pitot-static probe is use to determine the flow velocity by measuring the differential pressure. The pitot formula to obtain the flow velocity is, 2(P- P,) V = where, V is the velocity, P is pressure and pis fluid density. i) The pressure difference sensor use in the system is electronic types and the output of the device is measured in voltage. 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. An aircraft flying at 3000 m above sea level when the differential pressure reading clocked 3 kPa. Determine the speed of the aircraft.

Pipe Diameter Length f Location Elevation (mm) (m) (m) 1 750 500 0.0154 A 5.0 2 400 600 0.0177 B 4.5 3 500 650 0.0168 |C 4.0 700 400 0.0156 D 3.5 If the flow rate in pipe 1 is 2m³/s and the pressure at point A is 900kPa. Calculate the pressure at point D. Assume that the flows are fully turbulent in all pipes and specific weight of water, y = 9.79KN/m³
Flowrate adjusted with the rotameter together with the collected volume and time elapsed were written in the table below: Write down your measurements in a table: Readings on Duration Water collected in the rotameter (seconds) graduated cylinder (L/h) 800 1000 1200 1400 1600 1 8.320 2 6.770 3 6.160 4 5.180 5 4.470 Water temperature = 25 °C (mL) 1700 1700 1820 1800 1740 Calculated Flowrate (L/h) ➤ Display the variation in your experimental results with the readings from the rotameter by plotting a graph of calculated flowrate vs readings from the rotameter. Decide if a calibration constant is needed. How can you determine the value of calibration constant? Explain how it is used in your further experiments.
A flow meter sensor is connected to the microcontroller card to convert the signal and display it as a volume flow rate (L/min.) on the data show screen. Standard volume (graduated cylinder) with stopwatch were employed to calibrate the assemble system, and the calibration results were tabulated as following: Measuri L/min. 51 52 54.5 57 68 ng value Real L/min. 53 55 57 64 71 76 77 0 73 74 80 value Determine: 1- Absolute relative error (ARE). 2- Mean value, deviation (error) value and standard deviation (σ). 3- Draw the calibration curve.

According to these; 1. Calculate the pipe roughness height ( e ). 2. Calculate the Reynolds value. 3. Calculate the coefficient of friction f from the Darcy-Weisbach equation. 4. Briefly describe the equations you use and the reasons for using them.
