Question

A tank is divided into two sections by a 1 × 1-m square gate that is hinged at A A couple of magnitude 610 Nm 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 ρma_ 789 kg/m3) at the rate of 0.2 m3/min, determine when the gate will rotate. Round the final answer to one decimal place. 0.6 m Methyl Alcohol Water 0.4m 0.2 m The gate will rotate afterseconds.
