The outdoor and indoor temperature of a room are \(18^{\circ}\text{C}\) and \(22^{\circ}\text{C}\), respectively. There is also an internal heat gain of \(5\ \text{kW}\). Consider the volumetric heat capacity of air is \(1300\ \text{J/m}^3{\cdot}^{\circ}\text{C}\). Using the ventilation heat flow equation, the estimated rate of ventilation (in \(\text{m}^3\text{/s}\)) is (rounded off to two decimal places). Assume no other heat gains or losses and no net heat storage in the space.
