flued mechanics The inclined manometer at Fluid Dynamic laboratory at E5 has broken. You are tasked to design a new inclined manometer as shown in Figure 1. The design task is to decide what is the proper manometric fluid to be used, angle of inclination (θ), and the length of the vertical (L1) and inclined (L2) leg of the manometer. Since the manometer is mainly used together with Pitot-Static tube to measure air velocity it needs to be sensitive to a small pressure difference which in the range of 5 to 50 Pa. It should be notice that the manometer should fit in a compartment which has 15 cm-height and 80 cm-length. The inclination angle should be at least 5°. The temperature in the lab is around 27 °C to 37 °C. The manometric fluid should fulfil the following criteria: The fluid should have a low vapour pressure (A liquid with high vapour pressure would be less sensitive to changes in pressure) The fluid should have low surface tension to avoid the capillary rise. High boiling…

The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as Re = Duplu where Dis pipe diameter, u is fluid velocity, p is fluid density, and u is fluid viscosity. When the value of the Reynolds number is less than about 2100, the flow is laminarthat is, the fluid flows in smooth streamlines. For Reynolds numbers above 2100, the flow is turbulent, characterized by a great deal of agitation. Liquid methyl ethylketone (MEK) flows through a pipe with an inner diameter of 2.067 inches at an average velocity of 0.48 ft/s. At the fluid temperature of 20°C the density of liquid MEK is 0.805 g/cm? and the viscosity is 0.43 centipoise [1 cP = 1.00 x 10-³ kg/(m-s)]. Without using a calculator, determine whether the flow is laminar or turbulent. Show your calculations.
