In a capacitance spark the gas between the electrodes is heated almost instantaneously; subsequently, the spark‐generated heat flows from the gas to the material of the electrodes. In the present experiments sparks of 0.1 to 2 millijoules were passed between Pt electrodes in a bulb containing he...
As wind speed increases, so does the rate of heat loss from the nests of both species, and further still during incubation recesses. The significance of forced convection through the nest is a near-doubling in heat production required by the parent, even when incubating at relatively low wind...
The use of thermoelectric heat flow meters for measuring the heat flow through the skins of various animals was investigated under conditions of high solar radiation, and high and low air movements. A meter implanted surgically beneath the skin registered only a small proportion of the total heat...

The rate of heat loss can be calculated from Eq. (8.2-19), i.e., (1)Q˙=WH(TA−TB)1〈hA〉+Lk+1〈hB〉 The average heat transfer coefficients, 〈hA〉 and 〈hB〉, can be calculated from the correlations given in Table 4.2. However, the use of these equations requires the physi...
Analytical formulae are presented for the temperature and the heat loss for the case of a finite ground water flow rate. Both uninsulated and insulated ground slabs are studied. The formulae account for different thermal conductivities above and below the ground water table.Access through your org...

In this paragraph, we will go through an example of a BMR calculation for a man. We will have to use the BMR for man formula (Mifflin and St Jeor BMR equation for a man): BMR (kcal/day) = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (y) + 5 (kcal/day) Let'...
For an endothermic reaction, in which heat is consumed, ΔrH > 0. Table 3.2 shows orders of magnitude of the kinetic parameters for first-order reactions. The pre-exponential factor for a monomolecular reaction is about 1013 s− 1. Table 3.2. Orders of magnitude of the kinetic parameters ...
