Eq. 2
Here, \(p_{H_{2}O}\) is the partial pressure of water vapour in the
incubator, RH is the relative humidity (60%), and is the total pressure
of water vapour at 35.5 °C. Once the water vapour conductance was
calculated for these conditions, the water loss was calculated for the
standard conditions (25°C and 0% humidity) using the formula developed
by Ar et al., (1974):
\({\dot{M}}_{H_{2}O}=c*D_{H_{2}O}*\frac{\text{Ap}}{L}*P_{H_{2}O}\ \)
