Saturated liquid water at 1000 kPa flows at 2 kg/s inside a 10 cm outer diameter steel pipe and outside of the pipe is a flow of hot gases at 1000 K with a convection coefficient of h = 150 W/m2 K. Neglect any ΔT in the steel and any inside convection h and find the length of pipe needed to bring the water to saturated vapor.
