Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…

The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer, independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000 wafers. Assume a 20% annual interest rate for holding cost calculations. a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the optimal order quantity? b. If the replenishment lead time for wafers…
