WebHeat is form of energy, heat flows from a hotter area to cooler area until the bodies achieve thermal equilibrium. Or heat flows from a higher temperature section to lower … Web1) For the spoon dipped in hot oil the temperature at one end is 573 K and at another end is 325 K if the length of the spoon is 0.3 then find the temperature gradient present in a spoon. Given: T1= 573 K T2= 325 K x= 0.3 m By using the formula of temperature gradient, ∇T = dT/dx = (T2 – T1)/x ∇T = (325 – 573)/0.3 ∇T = – 826 K/m
Web27 apr. 2024 · Introduction. The heat transfer coefficient describes the convective heat transfer from a solid to a flowing fluid (gas or liquid) or vice versa. Such a situation can be seen, for example, with a radiator. Cold air flows past the radiator due free convection and is heated. Obviously, the radiator transfers heat to the passing air.
