Fluid Mechanics Flow Past a Circular Cylinder The behaviour of flow around and past bodies that are circular in the crosssection is very important‚ mainly because there are so many matching scenarios out there. Golf balls‚ over head cables and underwater supports are just a few examples of circular cross-sections and how studying flow in this case is important. Let us take golf balls for example‚ they have been engineered in such a way from them being perfectly round‚ to having small indents

return wind tunnel. The pressure tapings are connected to a multi-tube manometer‚ which is also used to measure the dynamic pressure. Students should check and record all the connections on the multitube manometer. Procedure: 1. Level and adjust the multitube manometer in the vertical position with the indicator registering 90 ‚ then incline it to approximately 40 to the horizontal. 2. Check and record all of the manometer connections. 3. Record the NACA aerofoil designation of the aerofoil

Manometer Definition A manometer measures the difference in air or liquid pressure by comparing it to an outside source‚ usually a sample of Earth’s atmosphere. There are several types of manometers piezometer tube‚ which is a single tube and a base that holds the liquid. U-shaped .

tappings upstream and downstream of the test pipe connect to a water manometer and a pressure gauge. The back panel holds the pressure gauge and a water manometer with calibrated scales. The water manometer measures lower differential pressures in the laminar and lower turbulent flow regions (just above the critical Reynolds Number). The pressure gauge measures higher pressures in the turbulent flow region. The water manometer includes an air valve and hand-pump. The hand-pump adjusts the datum

Chapter 3 Fluid Statics: Definitions Statics: ∑F = 0. In statics we have only pressure as surface force and weight as body force. Thus‚ when fluids are still‚ the pressure is balanced by the fluid weight. No relative motion between adjacent fluid layers. Shear stress is zero Only _______ can be acting on fluid surfaces Gravity force acts on the fluid (____ force) Applications: Pressure variation within a reservoir Forces on submerged surfaces Buoyant forces 9/4/2013 1 Pressure Pressure is defined

Firstly‚ water enters the apparatus through the lower left-hand end and flows through the Venturi Meter‚ followed by the Orifice meter then through 90o elbow and finally through the Rota Meter. All connections to the manometers panel are made from clear plastic tubes. Upon leaving the Rota Meter‚ the water flows via

The water flow through the apparatus is controlled by the delivery valve of the Hydraulics Bench and the flow rate may be confirmed by using the volumetric measuring tank of the Hydraulics Bench.

Water Traps and Pigtail Siphons A water trap is a device that allows gas and air to pass but holds back water. Pigtail Siphons Industrial factories utilize steam as a pressurized fuel for energy consumption. This steam needs to be regulated by a gauge‚ but the gauge must have a way of being safe from the powerful heat and pressure of the steam itself. This is where pigtail siphons (or siphons) come in. Function Pigtail siphons are looped pipes filled with water that are placed in piping configurations

Fluid Mechanics Laboratory 2 Report Robby Joseph 14103508 1.0 Introduction This experiment was undertaken for the study of flow in pipes and the factors that affect it in both laminar and turbulent regimes. The transitional regime between laminar and turbulent flow will also be studied. The experiment was done using a pipe with a known diameter‚ and water was pumped in from a tank. Throughout the process‚ measurements of the quantity of water and time were taken as well as the hydraulic gradient

Adjust the valves to obtain a flow rate so that the total head at the inlet approaches near maximum height on the manometer scale. 4. Place the pitot tube at the inlet of the Venturi tube and read the total head (Manometer #8). 5. Take manometer readings (Manometers #1 – #6) for the static heads at the six cross sections. 6.
