Number of fins in length L Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Fins = (2*Surface Area)/(pi*((Fin Diameter^2)-(Outer Diameter^2)))
NF = (2*A_s)/(pi*((FD^2)-(d_o^2)))
This formula uses 1 Constants, 4 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Number of Fins - The Number of Fins is the total count of the fins in length L.
Surface Area - (Measured in Square Meter) - Surface Area of a three-dimensional shape is the sum of all of the surface areas of each of the sides.
Fin Diameter - (Measured in Meter) - Fin diameter is the length from end of one fin to the end of opposite fin on the other side.
Outer Diameter - (Measured in Meter) - The Outer Diameter is the diameter of outer edge of circular hollow shaft.

STEP 1: Convert Input(s) to Base Unit

Surface Area: 0.52 Square Meter --> 0.52 Square Meter No Conversion Required
Fin Diameter: 0.3 Meter --> 0.3 Meter No Conversion Required
Outer Diameter: 0.26 Meter --> 0.26 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

NF = (2*A_s)/(pi*((FD^2)-(d_o^2))) --> (2*0.52)/(pi*((0.3^2)-(0.26^2)))

Evaluating ... ...

NF = 14.7786732871046

STEP 3: Convert Result to Output's Unit

14.7786732871046 --> No Conversion Required

FINAL ANSWER

14.7786732871046 ≈ 14.77867 <-- Number of Fins

What is Heat exchanger?

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.
