Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

A thin metal sheet serving the purpose of an an anemometer has a length of 2.5 cm with a width of 8 mm. Wind with a temperature T, and velocity Uz blows parallel to the longest side of the sheet. The metal sheet is heated through a solar powered system giving our heat both sides at Q Watts. The anemometer is used in air with T,= 20C, C, = 1.005KJ/Kg K, v = 1.522 X 105 m2/s, p = 1.19 Kg/m³ and Pr = 0.72. The surface temperature, T, of the metal sheet was measured at the rear end however, it can be assumed to be constant. You are required to calculate an estimate of the wind speed when T = 32 °C and Q = 0.5 W.
