Measurement of Air Flow Velocity in a Wind Tunnel Using a Pitot Tube

Table below shows the test data of the flow velocity (Q) and pressure drop (4P). Knowing that there is an offset of 0.03 in the flow measurement, the relation between the measured flow velocity and pressure drop is thus described as Q = avAP + 0.02, find the constant a for the best fit using Least- Square Method. (You can check your answer using excel, but will get NO point with only a value from excel without any procedures). Q (in³/sec) 0.17 0.20 0.26 AP (psi) 97 153 262

SAE 30 oil at 60 °F is pumped through a 2-ft-diameter pipeline at a rate of 6600 gal/min. A model of this pipeline is to be designed using a 4-in.-diameter pipe and water at 60 °F as the working fluid. To m Reynolds number similarity between these two systems, what fluid velocity will be required in the model? Vm ft/s the tolerance is +/-2%

CH, CQ and n are functions of CP. Draw the dimensionless performance curves of the turbine on a single graph by makingthe necessary scalings. (Fit the curve by using the excel program for drawing. Also give the values you used for plotting inthe table) ÖN=5

1) At any time, approximately 20 volcanoes are actively erupting on the Earth, and 50–70 volcanoes erupt each year. Over the past 100 years, an average of 850 people have died each year from volcano eruptions. As scientists and engineers study the mechanics of lava flow, accurately predicting the flow rate (velocity) of the lava is critical to saving lives after an eruption. Jeffrey's equation captures the relationship between flow rate and viscosity as: Flow V = Pgt sin(@) 28 сm 10 where p is the density of the lava, g is gravity, t is the flow thickness, a is the slope, and u is the lava viscosity. Typical values are given as follows for the flow rate: u= 4x103 kg/(m.s) ±1% p= 2.5 g/cm³ ±1% t= 28 cm +0.5 cm a= 10° +1 ° g= 9.81 m/s? Determine the likely maximum possible error in the calculated value of the flow rate.

Please check over this answer to see if there's anything wrong. (include step-by-step corrections if wrong)

Hi, Please help me with this question and please show the full solution. Thank you very much

56.0 mL of two different liquids are poured through a funnel with a narrow exit tube, and the time for all of the liquid to flow through is recorded. Here are some results: time to flow through funnel trial Liquid X Liquid Y 1.60 s 3.62 s 1.52 s 3.44 s 1.44 s 3.56 s Note: the two liquids have the same density. Which statement below is true about these liquids based only on the data in the table? O The intermolecular forces in liquid X are stronger than those in liquid Y. The boiling point of liquid X is higher than the boiling point of liquid Y. The viscosity of liquid X is greater than the viscosity of liquid Y. The surface tension of liquid X is greater than the surface tension of liquid Y. The viscosity of liquid X is less than the viscosity of liquid Y. 3.

Q.1 A simple and accurate viscometer can be made from a length of capillary tubing. If the flow rate and pressure drop are measured, and the tube geometry is known, the viscosity of Newtonian liquid can be computed. A test of a certain liquid in a capillary viscometer gave the following data: Flow rate: 880 mm /s, Tube length: 1 m, ,3, Tube diameter: 0.50 mm, Pressure drop: 1.0 MPа The viscosity of liquid will be (pig =999 kg/m:), assuming the flow to be laminar.
