Water at 290k flows at 0.5 m/s along a flat plate. for x < 10cm, t_s = 290k, whereas for 10 < x < 30 cm, t_s = 310k. calculate the local heat flux at x = 0.3 m. compare this result to the heat flux if the plate were isothermal at 310k. use equation 19-33 for nu_x for the plate with an unheated starting length. my printing of the book has a typo in this equation. the correct equation is nu_x 0.33 [pr/1 - (x/x)^3/4]^1/3 re_x^1/2
