an iron cube of 3cmm in length is initially at 25 ?C. the cube suspended in saturated steam stream at 120 ?C. using the following physical properties, calculate the time needed for the cube to reach 75 ?C.the convection heat transfer coefficient is 200W/m2 K. the density of iron is 7800 kg/m3the iron specific heat is 470J/kg.K
