Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

(You are tasked to supervise the design of 0.5MW wind turbine to be constructed in the 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 design specifications given, if the actual measurement of power via the substation amounts to exactly 530kW and given that the windspeed is off by 0.05m/s, what could have been the error in the measurement of diameter? Your answer must be in 3 decimal places and in correct signs and measurement.

A 50-cm wide wedge of 30° angle is used to deflect a flow of water (the width direction is into the paper). The incoming velocity of the water is 5 m/s and the water depth is 5 cm. Please compute the horizontal and vertical forces acting on the wedge from the water. In this example, water depth is shallow and you may neglect hydrostatic forces. Atmospheric pressure acts on the control volume from all directions and you do not need to consider atmospheric pressure, either, in the momentum balance. You may neglect frictions from the walls, too. 5 m/s 5 cm 5 cm Fx F y
