![]() Drag force: F_d = 0.5*rho*A*C_d*u^2, where rho is the density of air, A is the surface area of the plate, C_d is the drag coefficient, and u is the velocity of air. Convective heat transfer rate: Q = h*A*(T_s - T_∞), where A is the surface area of the plate, T_s is the surface temperature, and T_∞ is the free stream temperature. The Prandtl number can be found in the properties table. The Reynolds number can be calculated as Re = u*L/ν, where ν is the kinematic viscosity of air. For a flat plate subject to parallel flow, we can use the equation Nu = 0.664*Re^0.5*Pr^0.33, where Re is the Reynolds number and Pr is the Prandtl number. ![]() Average convection heat transfer coefficient: h = Nu*k/L, where Nu is the Nusselt number and L is the length of the plate. (a) For the flat plate subject to parallel flow with air, we can use the following equations:
