Energy Transfer Equation - The Engineering ToolBox
dt = temperature difference (rise or fall) in the substance (o C, K, o F) Example - Energy Transfer with Water 2 kg of water is heated from 20 o C to 60 o C .
Q = m Cp dT - ADG Efficiency
The temperature difference dT [°C] is the difference in temperature before and after heat transfer. Optimization of a hot water loop requires correctly setting the flow rate and temperature. We could use a high mass flow rate and low temperature difference. We could also use a low mass flow rate with a high temperature difference.
热力学方程dh=cp×dT在什么条件下能使用? - 知乎
热力学方程dh=cp×dT在什么条件下能使用? h是焓变，cp是定压比热容，照理说只能在等压变化的情况下使用。 但是在学空气动力学时这个式子在很多非等压变化下也能使用，比如我学一维定常等熵流动的能量方…
Confusion about heat transfer equations : r/AskEngineers - Reddit
2021年5月5日 · For the specific heat equation, m has units of (kg), Cp has units of (J/kg*K), and dT has SI units of (K). This means that the unit of Q is simply J. Through this dimensional analysis we can see that Fourier's law yields a value for the flow of heat through some surface, whereas the specific heat formula just describes how much energy (Q) is ...
Sensible heat can be calculated by the following equation Qmx Cpx DT …
To determine sensible heat, you must know both the mass of substance and the change of temperature (LT) in the substance. The specific heat capacity (Cp) is a constant that is characteristic of the substance. It represents the amount of energy that is gained or lost when the substance is equilibrated with environmental temperature.
