Result

Required heat transfer area
— m²

Enter positive heat duty, coefficient and effective temperature difference. This tool does not calculate correction factors.

Equation

A = |Q̇| / (U · ΔTeffective)

Enter positive heat duty, coefficient and effective temperature difference. This tool does not calculate correction factors.

Applicability

  • A preliminary estimate using known duty, overall coefficient and effective temperature difference.
  • The coefficient and temperature difference must match the selected area basis and operating conditions.
  • Evaluate multipass correction, fouling, design allowance and mechanical design separately.

Worked example

Example: 100,000 W, 500 W/(m²·K) and 20 K give an area of 10 m².

For engineering estimates; check the operating conditions and applicable requirements for design.
