BME-027(S) HEAT AND MASS TRANSFER
Time 3 hours Maximum Marks: 70
Note: Answer any Beven questions. All questions carry equal marks. Use of scientific calculator is permitted.
1. State and explain Fourier's law of heat conduction. 5
Explain the principle of heat convection with suitable examples. 5
2. Give the classification of heat exchangers. Explain the working principle of plate fin heat exchanger
Explain the phenomenon of temperature distribution in heat exchangers. 5
3. Steam at a temperature of 380°C is flowing in a pipe 100 W/m of 8 cm inner diameter and 8.5 cm outer diameter. The pipe is covered with 10 cm thick insulation of thermal conductivity K =0.15 W/m K .Heat is lost to the surroundings at 8°C by natural convection and radiation, the combined h being 40 W/m2 K .Taking the heat transfer coefficient inside the pipe as 40 W/m2 determine
the rate of heat loss from the steam per unit length of the pipe, and
the temperature drop across the pipe and the insulation. 10
4. Explain the working principle of a 'Fire Tube Boiler' with a diagram. 5
What is a fin Explain why fins are attached to a heat exchanger. 5
5. Derive the general mass diffusion equation for a Cartesian coordinate system. 10
6. What is meant by evaporation With the help of a neat diagram, explain the working principle of a single effect evaporator with sketch. 5
Derive Planck's law. 5
7. What is Sherwood number? 3
Using dimensional analysis, establish the relationship between the Sherwood number, Reynolds number and Schmidt number. 7
8. Define the following terms
Emissivity
Black body
Spectral intensity 6
Derive Wein's displacement law. 4
9. Explain the following in detail:
Laminar Flow and Turbulent Flow
Film Condensation
