Number of fins given perimeter Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Fins = (Perimeter-2*Height of Crack)/(4*Fin Length)
NF = (P-2*h_c)/(4*FL)
This formula uses 4 Variables

Variables Used

Number of Fins - The Number of Fins is the total count of the fins in length L.
Perimeter - (Measured in Meter) - The perimeter of a figure is the total distance around the edge of the figure.
Height of Crack - (Measured in Meter) - Height of Crack is the size of a flaw or crack in a material that can lead to catastrophic failure under a given stress.
Fin Length - (Measured in Meter) - Fin length is the length of the fin.

STEP 1: Convert Input(s) to Base Unit

Perimeter: 25 Meter --> 25 Meter No Conversion Required
Height of Crack: 12000 Millimeter --> 12 Meter (Check conversion here)
Fin Length: 0.04 Meter --> 0.04 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

NF = (P-2*h_c)/(4*FL) --> (25-2*12)/(4*0.04)

Evaluating ... ...

NF = 6.25

STEP 3: Convert Result to Output's Unit

6.25 --> No Conversion Required

FINAL ANSWER

6.25 <-- Number of Fins

Number of tubes in transverse fin heat exchanger

Go Number of Tubes = Mass Flow Rate/(Mass Flux(g)*Distance between two Consequent Tubes*Height of Crack)

Distance between two consequent tubes in transverse fin heat exchanger

Go Distance between two Consequent Tubes = Mass Flow Rate/(Mass Flux(g)*Number of Tubes*Length)

Length of tube bank

Go Length = Mass Flow Rate/(Mass Flux(g)*Number of Tubes*Distance between two Consequent Tubes)

Equivalent diameter of tube for transverse fin heat exchanger

Go Equivalent Diameter = (Reynolds Number(e)*Viscosity of Fluid)/(Mass Flux)

Number of fins given perimeter Formula

Number of Fins = (Perimeter-2*Height of Crack)/(4*Fin Length)
NF = (P-2*h_c)/(4*FL)

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.
