The drag force on an airship must be determined by testing with a reduced-scale model. The tests are carried out in a water tunnel, where the airship model is fixed to a support instrumented with a force sensor. The speed of the flow that affects the model is controlled by a variable speed pump that is the one that originates the flow towards the model. The scale is 1:20, μwater=1.01x10-3 kg/ms, μair= 1.85x10-5 Pa-s, ρair= 1.25kg/m3, ρwater=1000 kg/m3. Determine: a) the dimensionless numbers of the situation b) The VM if VP=36km/h c) The power of the prototype airship if FM= 1 649 N.

PROPAGATION OF ERROR You are tasked to supervise the design of 0.5MW wind turbine to be constructed in a Wind Farm in Pililla, Rizal. Suppose the design criteria are as follows: The air density as surveyed after 2 year period averaged at 1.225 kg / cubic meter. The sweeping diameter of the rotor blades is 125m, and the anemometer reading in the area amounts to 4.2m/s on a 2 year period of survey. What is the theoretical power output of the turbine assuming 100% efficiency of operation? Your answer must be in kW and in two decimal places with correct signs.  In the previous problem, if the diameter measurement is off by 0.1m and the anemometer reading is also fluctuating by 0.05m/s and if the error measurement for theoretical power output must be limited to 3%, WHY OR WHY NOT should you accept the design? * Show complete solution in paper.

Q 12

You are working for a medical device start-up company as a design engineer. Your first task is to make measurements on the flow of blood plasma through your prototype. The device specifications require that 37°C plasma flow into the device pass through a bank of 100 tubes (0.2mm diameter), then exit the device. The total flow rate for the device must be 800 ml min^-1. If you want to maintain a pressure drop across each tube below 100 pascals, what is the maximum length of the tube in centimeters?

4. Liquid Flow. A cylindrical tank of diameter D is filled with water to a height h. Water is allowed to flow out of the tank through a hole of diameter d in the bottom of the tank. The differential equation describing the height of water in the tank as a function of time is d? /2gh D? dh dt where g is the acceleration due to gravity. Produce a plot of height of water in the tank as a function of time for D = 10 ft, d = 6 in and ho = 30 ft. Compare your results with the analytical solution h=(/ho - kt/2} , where k= (d² / D')/2g.

Describe the methodology for obtaining the pump curve in a project, where data are collected at five points with different pressures in the pump (10 psi, 15 psi, 20 psi, 25 psi and 30 psi), where to find these flow rates Q a 1000 ml bottle is used and the time required to fill it is timed,  for each of the pump's five pressure points. The gauge pressure H in meters of water column reached must also be observed in order to construct the HxQ graph of the pump. This entire process is carried out for three different types of piping systems, each with its characteristic pressure drops.

A Pitot-static probe was used to measure the velocity distribution in a water tunnel. The two pressure lines from the probe were connected to a U-tube manometer which uses a liquid of specific gravity 1.7. The maximum velocity expected in the water tunnel was 2.3 m/s. Your job was to select an appropriate U-tube from a manufacturer which supplies manometers of different heights. The cost increases significantly with manometer height. Which of these should you purchase?
