In a shell and tube heat exchanger, tube side _______________ of the mass velocity?
Correct answer: C. Both A. & B.
- A. Heat transfer co-efficient is proportional to 0.8th power
- B. Pressure drop is proportional to the square
- C. Both A. & B.
- D. Neither A. nor B.
Explanation
For turbulent flow in the tube side, the heat-transfer coefficient commonly varies approximately as mass velocity to the 0.8 power, while frictional pressure drop varies approximately with the square of mass velocity. Therefore both statements are correct.
