Sample Problem Solutions
Here are a few sample problem solutions from the manual:
Problem 1.4 (Page 15)
A steel plate with a thickness of 5 cm and a thermal conductivity of 50 W/m°C is heated to a uniform temperature of 500°C. The plate is then exposed to a fluid at a temperature of 100°C, with a convective heat transfer coefficient of 100 W/m²°C. Calculate the heat transfer rate per unit area.
Solution
Using Newton's law of cooling:
q = h(Ts - T∞)
where q is the heat transfer rate per unit area, h is the convective heat transfer coefficient, Ts is the surface temperature, and T∞ is the fluid temperature.
Assuming the surface temperature is approximately equal to the initial plate temperature:
q = 100 W/m²°C × (500°C - 100°C) = 40,000 W/m²
Problem 3.2 (Page 65)
A solid cylinder with a diameter of 10 cm and a length of 20 cm is initially at a uniform temperature of 200°C. The cylinder is then suddenly exposed to a fluid at a temperature of 50°C, with a convective heat transfer coefficient of 50 W/m²°C. Calculate the temperature at the center of the cylinder after 10 minutes.
Solution
Using the lumped parameter model:
T(t) = T∞ + (T0 - T∞)exp(-hAt/ρVc)
where T(t) is the temperature at time t, T∞ is the fluid temperature, T0 is the initial temperature, h is the convective heat transfer coefficient, A is the surface area, ρ is the density, V is the volume, and c is the specific heat capacity.
Assuming the density and specific heat capacity of the cylinder material are 8000 kg/m³ and 500 J/kg°C, respectively:
T(10) = 50°C + (200°C - 50°C)exp(-50 W/m²°C × π × 0.1 m × 0.2 m / (8000 kg/m³ × (π/4) × 0.1² m² × 0.2 m × 500 J/kg°C) × 600 s) ≈ 143°C

Example Problems and Solutions
Here are a few example problems and solutions from the book:
Problem 1
A heat exchanger is used to cool a stream of oil from 200°C to 100°C. The oil flows through a tube with a diameter of 0.1 m and a length of 10 m. The heat transfer coefficient is 500 W/m²K. What is the rate of heat transfer?
Solution
Using the equation for convection heat transfer:
Q = h * A * ΔT
where Q is the rate of heat transfer, h is the heat transfer coefficient, A is the surface area, and ΔT is the temperature difference.
Q = 500 W/m²K * π * 0.1 m * 10 m * (200°C - 100°C) = 314,159 W Importance of Heat Transfer in Industrial Processes Heat
Problem 2
A condenser is used to condense steam at a pressure of 10 bar. The condenser is cooled by water flowing through a tube with a diameter of 0.05 m and a length of 5 m. The heat transfer coefficient is 2000 W/m²K. What is the rate of heat transfer?
Solution
Using the equation for convection heat transfer:
Q = h * A * ΔT
where Q is the rate of heat transfer, h is the heat transfer coefficient, A is the surface area, and ΔT is the temperature difference.
Q = 2000 W/m²K * π * 0.05 m * 5 m * (100°C - 20°C) = 157,080 W
These example problems and solutions illustrate the types of calculations that can be performed using the principles and equations presented in the book.
The classic textbook Process Heat Transfer by Donald Q. Kern (D.Q. Kern) is widely considered the "gold standard" for chemical and process engineering. First published in 1950, it provides a rigorous, applied approach to designing industrial heat exchangers, bridging the gap between theoretical heat transfer and practical engineering. Role of the Solution Manual
Because Kern's methodology is complex and involves extensive empirical calculations, the Solution Manual is an essential companion for both students and practicing engineers. It provides:
Step-by-Step Guidance: Breaks down multi-layered problems into logical calculations, particularly for industrial designs like shell-and-tube or double-pipe heat exchangers.
Clarification of Concepts: Expands on difficult topics such as fouling factors, unsteady-state conduction, and pressure drop considerations.
Practical Application: Demonstrates how abstract formulas translate into the standardized "Kern method" used for professional equipment design. Content Overview
The solutions typically align with the textbook's three-part structure:
Fundamental Principles: Conduction, convection, and radiation solutions.
Heat Exchanger Design: Meticulous work-throughs for the "meat" of the book—designing double-pipe, shell-and-tube, and extended-surface exchangers.
Advanced Equipment: Solutions for boilers, condensers, cooling towers, and newer topics like risk assessment in the 2nd edition. Availability and Access
Finding a physical copy of the official solution manual can be difficult as it was originally intended for instructors. However, digital versions and community-verified solutions are often hosted on academic and document-sharing platforms:
Educational Platforms: Sites like Scribd and Google Drive archives often host PDF versions of the manual or student-compiled solution sets.
Libraries: Check for digital lending through platforms like Open Library or your local university library catalog.
Modern Editions: The updated Kern's Process Heat Transfer (2nd Edition, 2019) by Ann Marie Flynn and others is available for purchase through Walmart or VitalSource, and may have more readily accessible supplementary materials. Conclusion The solution manual for "Process Heat Transfer"
