The extent to which the tip condition affects the thermal performance of a fin depends on the fin geometry and thermal conductivity, as well as the convection coefficient. consider an alloyed aluminum (k = 180 w/m*k) rectangular fin of length l= 10 mm, thickness t = 1 mm, and width w > > t. the base temperature of the fin is tb= 100°c, and the fin is exposed to a fluid of temperature t[infinity]= 25°c. assuming a uniform convection coefficient of h = 100 w/m2*k over the entire fin surface, determine the fin heat transfer rate per unit width qf’, efficiency ηf, effectiveness εf, thermal resistance per unit width r’t, f, and the tip temperature t(l) for

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Air undergoes a constant pressure cooling process with no moisture added or removed. the air originally exists at 45 °c, 150 kpa and 35 % relative humidity. it is cooled until the temperature reaches 29 oc. determine (a) the relative humidity of the cooled air. (b) the dew point temperature of the cooled air in °c. (c) the heat removed during the cooling process in kj/kg. use the psychrometric chart to check your answers (this part will not be graded; however, it will you get comfortable using the psychrometric chart)
