Number of Tubes in Center Row Given Bundle Diameter and Tube Pitch Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Tubes in Vertical Tube Row = Bundle Diameter/Tube Pitch
N_r = D_B/P_Tube
This formula uses 3 Variables

Variables Used

Number of Tubes in Vertical Tube Row - Number of Tubes in Vertical Tube Row is defined as the tubes that are placed exactly in the center/Vertical Orientation of the tube bundle layout.
Bundle Diameter - (Measured in Millimeter) - Bundle Diameter refers to the diameter of the tube bundle within the heat exchanger.
Tube Pitch - (Measured in Millimeter) - Tube Pitch in a heat exchanger refers to the center-to-center spacing between adjacent tubes in a tube bundle of heat exchanger.

STEP 1: Convert Input(s) to Base Unit

Bundle Diameter: 542 Millimeter --> 542 Millimeter No Conversion Required
Tube Pitch: 23 Millimeter --> 23 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N_r = D_B/P_Tube --> 542/23

Evaluating ... ...

N_r = 23.5652173913043

STEP 3: Convert Result to Output's Unit

23.5652173913043 --> No Conversion Required

FINAL ANSWER

23.5652173913043 ≈ 23.56522 <-- Number of Tubes in Vertical Tube Row

What is Shell and Tube heat exchanger?

A Shell and Tube Heat Exchanger is a common type of heat exchanger used in various industrial applications to transfer heat between two fluids. It consists of a large, cylindrical outer shell (usually made of metal) with multiple smaller tubes (also made of metal) running through it. The tubes are arranged in a bundle inside the shell and are typically oriented parallel to the shell's longitudinal axis.

What is the significance of number of tubes?

The number of tubes in a heat exchanger is a critical design parameter that significantly impacts the performance and characteristics of the heat exchanger. The number of tubes directly influences the total heat transfer area of the heat exchanger. More tubes mean a larger surface area for heat exchange between the hot and cold fluids. This leads to improved heat transfer efficiency and better overall performance.

The number of tubes in the central rows is a crucial parameter for designing of the condensers as it forms the basis of tubes that are effectively in contact with the vapor and the condensate.
