In adiabatic process , no heat crosses the boundaries of the system. Therefore no heat transfer takes place in adiabatic process.

This answer needs to be elaborated with the help of diagrams and unfortunately we cannot draw or attach images or files here. There are various Characteristics that affect the resistance ti heat transfer in refrigerators. They include Refrigerant mass flow rate and refrigerent properties.The heat transfer resistance might change more

Dear student,

Heat is transferred by direct contact of bodies or substances in conduction.

Conduction means - the transfer of heat between bodies that are in direct contact with each other.

When a substance is heated, the particles will gain more energy, and vibrate more. These molecules collide with other

Hi,

Your query seems incomplete.

1. The convective heat transfer coefficient in laminar flow over a flat plate a) Increases with distance b) Increases if a higher viscosity fluid is used c) Increases if ...

However the correct answer would be that the convective heat transfer coefficient in laminar flow

Hello student,

The question related to correlations for forced convection is that-

Q. The convective heat transfer coefficient in laminar flow over a flat plate;

a) Increases with distance

b) Increases if a higher viscosity fluid is used

c) Increases if a denser fluid is used

d) Decreases with increase

Gay-Lussac's Law: The Pressure Temperature Law. This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature . With an increase in temperature , the pressure will go up.

hello aspirant,

For an ideal gas, the temperature remains constant because the internal energy only depends on temperature in that case. Since at constant temperature, the entropy is proportional to the volume, the entropy increases in this case, therefore this process is irreversible.  An example of an isobaric system is

hello aspirant,

a b.tech final year or pass out student can apply in gate from any stream. even a mechanical engineer can opted for computer science engineering branch. however the preparation is only depends on you that how well can you prepare. now coming to your point, you may apply
