A fan is used to extract the flue gasfrom the fire via a chimney made of zinc material. The wall thickness of Chimney is L=4mm and the walltemperature of the chimney on the flue gas side is T_si=60˚C. Sipho, playing outside next to the chimneyexperiences an ambient temperature of 20˚C. The surrounding temperature is T_sur=35˚C and the emissivityis ε=0.95. Assume the convection coefficient is 20W/m2K and the chimney is grey material.Under these conditions determine the outer surface (air side) temperature T_so=? of the chimney.arrow_forwardAnswer this ASAP The diameter of the tube is 25 mm.

- Need answer step by step! THANKSarrow_forwardQ1: Water at 80 oC is pumped through 100 m of stainless steel pipe, k=16 W/m.K of inner and outer radius 47 mm and 50 mm respectively. The heat transfer coefficient due to water is 2000 W/m2.K. The outer surface of the pipe loses heat by convection to air at 20 oC and the heat transfer coefficient is 200 W/m2.K. Calculate the heat flow through the pipe. Also calculate the heat flow through the pipe when a layer of insulation, k=0.1 W/m.K and 50 mm radial thickness is .wrapped around the pipearrow_forwardQ2) Derive an equation for the temperature profile in the wall and calculate the temperature at the solid-fluid interface for the one-dimensional heat transfer problem schematically shown below. Heat is volumetrically generated within the wall. The thickness of the wall is L. A fluid flows on the left side of the wall while the right side is insulated. The convective heat transfer coefficient is h, the temperature and velocity of the fluid is To and Væ, respectively. Given that, L= 30 mm, k =7 W/m K, h = 400 W/m2.K, T = 25°C, q = 1.00xl06 W/m³.

- Q2/ A small horizontal plate is in the shape of a square with a length of 5 cm. The plate is maintained at 50 C and exposed to water at 15 C. Calculate the heat loss.arrow_forwardSaturated steam at 3 atm will flow through a 3 in. Schedule 80 steel pipe. In order todecrease the heat losses to the surrounding air (at 20 oC) the pipe will be insulated. There are twotypes of insulating materials available, each with a thickness of 2.5 cm. Thermal conductivity ofinsulator A is 0.04 W/m.K and that of insulator B is 0.20 W/m.K. Both insulators will be used, inorder to have the least heat loss. Which insulator should be covered outside? Assume thatconvective heat transfer coefficient between the insulated pipe and air is 15 W/m2K.arrow_forwardonly part 1d)arrow_forward
