1. Nitrogen at 50F and 1atm. flows at a velocity of 5ft/s. A flat plate of 6ft. length, held at a uniform temperature of 150F, is aligned parallel to the direction of flow. Determine (a) hx (local heat transfer coefficient) at the downstream end (i.e., at x=6ft.) of the plate (b) average h (over the entire length of the plate) and (c) total heat transfer rate (assuming unit width)
