How does the science of heat transfer differ from the science of

The difference between science of heat transfer and science of thermodynamics.
Explanation of Solution
Heat transfer is defined as the science which deals with the rate of transfer of energy. It tells about the basic information of the amount of heat transfer at a specified instantaneous time. Transfer of heat occurs when there is difference in the temperature of the body and the surroundings. It does not achieve equilibrium stage as heat transfer is a non-equilibrium phenomenon.
Whereas,the science of thermodynamics deals with the amount of heat transfer when a system experiences state change. It does not give any information about the rate of energy transfer.
Thermodynamics system does not give any information related to the nature of the state change.Heat transfer takes place from the region of higher temperature to the region of low temperature.

Im unsure if it is correct, so looking for a checkover. i am stuck on the part tan-1 (0.05) = 0.04996 radians. Just unsure where the value for the radians came from. Just need to know how they got that answer and how it is correct before moving on to the next part. If any of the below information is wrong, please feel free to give me a new answer or an entire new explanation. An Inclining experiment done on a ship thats 6500 t, a mass of 30t was moved 6.0 m transvesly causing a 30 cm deflection in a 6m pendulum, calculate the transverse meta centre height. Here is the step-by-step explanation: Given: Displacement of the ship (W) = 6500 tonnes = 6500×1000=6,500,000kg Mass moved transversely (w) = 30 tonnes=30×1000=30,000kg The transverse shift of mass (d) = 6.0 meters Pendulum length (L) = 6.0 meters Pendulum deflection (x) = 30 cm = 0.30 meters Step 1: Formula for Metacentric Height…arrow_forward
