1. To calculate the temperature difference in a double pipe heat exchanger, we use _____

2. In the calculation of Friction Factor on the annulus/tube side for heat transferred, which is the correct formula for Friction Factor?

3. Consider we have a Double Pipe Heat Exchanger, with the inner tube of Outer diameter 20mm (thickness 2mm) and outer tube of inner diameter 30mm. We have two fluids A & B, both of density 990 Kg/m3, we desire to have their flow rates as 15m/s and 21m/s respectively, friction factor of 0.00096 and 5 hairpins of length 0.4 metre. What is the value of Pressure drop for the inner tube?

4. Which one of the following fluid cannot be placed in the tube side?

5. To calculate the temperature difference in a Shell and tube heat exchanger, we use _____

6. In a shell and tube heat exchanger, in the inner side fluid enters at 15℃ and leaves at 65℃. The shell has steam at 1atm. What is the value of corrected LMTD and correction factor?

7. In a shell and tube heat exchanger, in the inner side fluid enters at 15℃ and leaves at 65℃. The shell has oil entering at 105℃ and leaving at 85℃. What is the value of correction factor coefficients R and P?

8. In a 1-2 Shell and Tube heat exchanger, how many concurrent and counter current flow regimes are observed?

9. What is the unit of Fouling factor (Rf) in F.P.S system?

10. What is the equivalent diameter of a triangular pitch shell and tube HE if pitch is 40mm, the outer diameter of the tubes is 30mm?
