A reactor's wall 320mm thick, is made up of an inner layer of fire brick (k = 0.84W/m°C) covered with a layer of insulation (k = 0.16W/m°C). The reactor operates at a temperature of 1325°C at the atmospheric temperature of 25°C. i. Calculate the thickness of brick and insulation. ii. Heat loss per unit area presuming that the insulating material has a maximum temperature of 1200°C.

In the resistance strain gauge arrangement of Fig. 4.1 strain gauge resistance R1 = R2 = R3 = R4= 120 Ω Eb = 9 V. If the output voltage of the bridge is 20 mV, find the value of force applied to the strip. Thickness t of the strip = 1 mm. Width b of strip = 10 mm. Young's modulus E of strip material = 8 x 1010 N/m2. Length L = 50 mm. Strain at root of cantilever = 6PL/Ebt2. Assume output resistance as infinity. Gauge factor = 2.4.
