3. Water at 300 K and a flow rate of 5 kg/s enters a black, thin-walled tube, which passes through a large furnace whose walls and air are at a temperature of 700 K. The ot be diameter and length of the tube are 0.25 m and 8 m, respectively. Convection coefficients associated with water flow through the tube and airflow over the tube mist are 300 W/m² K and 50 W/m². K, respectively. Ignore water tube wall thickness and resistance. Water m = 5 kg/s 100Tm,i = 300 K vilu -Tube, D = 0.25 m L=8m, & 1 Air T=700 K Imo Furnace, Tur 700 K 1537 Ignore radiation between the tube and its surrounding, i.e., only consider the convection from the hot air as far as external heat transfer is concerned, please calculate the outlet temperature of the water flow, Tm.o
