Homework Statement A thin flat plate 2m×2m is hanging freely in air. The temperature of the surroundings is 25°C. Solar radiation is falling on one side of the plate at the rate of 500 W/m2. What should be the convective heat transfer coefficient in W/m2°C, if the temperature of the plate is...

Hello, i have a simple question regarding a problem I am solving. Here it is: A 4x4m flat plate maintained at a constant temperature of 80 degree Celsius subjected to parallel flow of air at 1 atm,20 degree celsius and 10m/s.The total drag force acting on the UPPER surface of plate is measured...

According to wikipedia, "the related notation [hkℓ] denotes the direction: h \mathbf{a}_1 + k \mathbf{a}_2 + \ell \mathbf{a}_3 .( That is, it uses the direct lattice basis instead of the reciprocal lattice. Im just confused why are the solution using the reciprocal meant for...
