Dry and saturated steam at 6 MPa abs. enters a 40 m length of 11.5 cm O.D steel pipe at a flow rate of 0.12 kg/s. The pipe is covered with 5 cm thick asbestos insulation (k= 0.022 W/m-K). The pipe is located in a tunnel with stagnant air temperature of 27°C. The unit outside convective coefficient is 10 W/m^2-K. Neglecting steam film and pipe wall resistance, determine the mass of steam.
