Atank is divided into two sections by a 1 × 1-m square gate that is hinged at a. a couple of magnitude 570 n·m is required for the gate to rotate. if one side of the tank is filled with water at the rate of 0.1 m3/min and the other side is filled simultaneously with methyl alcohol (density rhoma = 789 kg/m3) at the rate of 0.2 m3/min, determine when the gate will rotate. round the final answer to one

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
