This calorimeter has been used for measuring the rate of heat production of unbuffered bull semen under anaerobic conditions and although the calorimeter was not ideally suited to the work some results have been obtained which might be of interest to workers in the field of fertility....
The rates of oxygen consumption by young Friesian cattle were measured before, during, and after consumption of cut or standing pasture; the animals were restrained in a paddock during these measurements. Mean increases in heat production during eating were 2.38 and 2.80 kJ/h per kg LW for the...
There are several ways to calculate the heat release rate of a material. A good approximation can be determined by the formula: qHc= ΔHcx mfuel where: qHc= the heat release rate (kJ/s) ΔHc= the heat of combustion (MJ.kg-1) ...

The Joule heat production rate and the particle energy injection rate as a function of the geomagnetic indices AE - Ahn, Akasofu, et al. - 1983 () Citation Context ...heating rates can be difficult to ascertain. Instead, the geomagnetic auroral electrojet (AE) indices are often used as a...
The effectiveness is defined as the ratio of the actual heat transfer rate to the thermodynamically limited maximum heat transfer rate in a counter flow heat exchanger of infinite surface area. From: Transport Phenomena in Heat and Mass Transfer, 1992 ...
Ao et al. [103] proposed a formula (Eq. (9)) to calculate the minimum airflow rate of range hoods based on the mass conservation that was appropriate to all types of kitchens including residential kitchens: (9)qv=Lrtr−αzVαctc where Lr (m3/s) is the flow rate of the pollutant...
3.3.5 Relationships Between Reaction Rate and Net Rate of Production When interpreting information from kinetic measurements one should take into account that there is a difference between the measured value of the net rate of production of component i, Ri, and the reaction rate, r. For a singl...
