Q. A liquid flowing through a tube is turbulent. In which case will the maximum change in heat transfer coefficient occur? (Solved)
1. Diameter of the tube is increased 4 time maintaining the ratio of liquid flow constant
2. Diameter of the tube is increased 4 times maintaining the velocity of flow constant
3. Diameter of the tube is increased 2 times maintaining the rate of liquid flow constant
4. Diameter of the tube is increased 2 times maintaining the velocity of flow constant
5. microns
- a. Diameter of the tube is increased 4 time maintaining the ratio of liquid flow constant
