Mechanical Engineering :: Heat and Mass Transfer
- Which of the following is a case of steady state heat transfer?
- Radiation is the process of heat transfer in which heat flows from a ________, in a straight line, without affecting the intervening medium.
- Fourier's law of heat conduction gives the heat flow for
- In a shell and tube heat exchanger, baffles are provided on the shell side to
- A designer chooses the values of fluid flow rates and specific heats in such a manner that the heat capacities of the two fluids are equal. A hot fluid enters the counter flow heat exchanger at 100°C and leaves at 60°C. A cold fluid enters the heat exchanger at 40°C. The mean temperature difference between the two fluids is
- If the energy radiated per second per sq. cm. of the surface for wave lengths lying between λ, and λ + dλ is represented by (eλ.dλ), then eλ is called
- The process of heat transfer from one particle of the fluid to another by the actual movement of the fluid particles due to difference of density caused by temperature of the particle is known as
- The process of heat transfer from one particle of the body to another by the actual motion of the heated particles, is called
- Fourier's law of heat conduction is valid for
- According to Newton's law of cooling, the heat transfer from a hot body to a cold body is
