Number of Tubes in Eight Pass Triangular Pitch given Bundle Diameter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Tubes = 0.0365*(Bundle Diameter/Pipe Outer Diameter)^2.675
N_Tubes = 0.0365*(D_B/D_Outer)^2.675
This formula uses 3 Variables

Variables Used

Number of Tubes - Number of tubes in a heat exchanger refers to the count of individual tubes that form the heat transfer surface inside the heat exchanger.
Bundle Diameter - (Measured in Meter) - Bundle Diameter refers to the diameter of the tube bundle within the heat exchanger.
Pipe Outer Diameter - (Measured in Meter) - Pipe Outer Diameter refers to the measurement of the outside or external diameter of a cylindrical pipe. It includes the pipe thickness into it.

STEP 1: Convert Input(s) to Base Unit

Bundle Diameter: 542 Millimeter --> 0.542 Meter (Check conversion here)
Pipe Outer Diameter: 19 Millimeter --> 0.019 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_Tubes = 0.0365*(D_B/D_Outer)^2.675 --> 0.0365*(0.542/0.019)^2.675

Evaluating ... ...

N_Tubes = 285.151114535073

STEP 3: Convert Result to Output's Unit

285.151114535073 --> No Conversion Required

FINAL ANSWER

285.151114535073 ≈ 285 <-- Number of Tubes

(Calculation completed in 00.020 seconds)

What is Bundle Diameter in Heat Exchanger?

The bundle diameter in a shell and tube heat exchanger is the diameter of the tube bundle, which is a critical component influencing heat transfer efficiency, pressure drop, and maintenance considerations. In a single pass design/1-Tube pass, fluid flows through the tubes only once. The inlet of one fluid is connected to one end of the tubes, and the outlet is connected to the other end. This design is simple and suitable for applications where a moderate level of heat transfer is required.

What is Triangular Pitch?

Triangular Pitch Pattern is the shape of accommodating the tubes in the shell and tube Heat Exchanger. This pattern is used when the fluid in tube side is corrosive/ fouling. Triangular Pattern Tube Pitch provides the Highest heat transfer Coefficient among all patterns available.
