After the box girder was poured, the cement hydration generated heat and produced a large temperature difference in the girder, which may lead to the cracking. In order to study the hydration heat distribution and cracking risk of three-cell girder after pouring, the scale model of box girder was poured, 258 temperature sensors, solar radiation sensors and wind .
I have a box (as shown below). I know the temperature outside of the box (for example you could use 293K) and I would assume the temperature inside the box is initially the same as outside of the box. I have 6000 chickens in the box. They produce a total of 15.8 W of heat with 8 W of that being sensible heat.Temperature distribution during microwave reheating was studied with different food models: 10% starch gel in family-serving size microwavable dishes and two laboratory-formulated food products (spaghetti with meat sauce, rice and salmon with white sauce) similar to commercial sous vide products in small trays.
HT-7 ∂ ∂−() −= f TT kA L 2 AB TA TB 0. (2.5) In equation (2.5), k is a proportionality factor that is a function of the material and the temperature, A is the cross-sectional area and L is the length of the bar. In the limit for any temperature difference ∆T across a length ∆x as both L, T A - T B → 0, we can say dx dT kA L T T kA The temperature distribution in the considered plate in an analytical form was obtained using the time-dependent Green’s function. The advantage of this approach is that a solution without any additional simplification can be obtained. Numerical calculation of the temperature distribution were performed using the analytical form of the solution.
