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: Solution Manual Of Process Heat Transfer By D Q Kern Hitl
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
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.
Finding a reliable Solution Manual for "Process Heat Transfer" by Donald Q. Kern is a common quest for chemical and mechanical engineering students. Kern’s textbook is a cornerstone of heat exchanger design, but its problems are notoriously complex, often requiring iterative calculations that can take hours to solve by hand. Why Kern’s "Process Heat Transfer" is a Legend
First published in 1950, Donald Q. Kern’s work remains the industry standard for practical heat transfer. Unlike more theoretical modern texts, Kern focuses on industrial applications:
Shell and Tube Exchangers: The "Kern Method" is still taught globally for calculating pressure drops and heat transfer coefficients.
Double Pipe Exchangers: Simplifies the logic for 1-2 and 2-4 pass systems.
Condensation and Boiling: Provides empirical correlations that bridge the gap between lab theory and plant reality. What’s Inside the Solution Manual?
A comprehensive solution manual (often sought under the "Hitl" or "HIT" tags in digital archives) typically provides:
Step-by-Step Iterations: Many problems in Kern require guessing a heat transfer coefficient (
) and then refining it. The manual shows the logic behind these trials.
LMTD Corrections: Detailed calculations for the Log Mean Temperature Difference correction factor ( Ftcap F sub t
Property Evaluation: Guidance on at what temperatures to evaluate fluid properties like viscosity, thermal conductivity, and density (caloric temperature vs. average temperature). The "Hitl" Connection
The term "Hitl" or "Hit" in search queries often refers to specific digitized versions or legacy academic repositories (like Scribd or specialized engineering forums) where these manuals were first uploaded. Because the book is an older classic, many "manuals" are actually handwritten sets of solutions compiled by professors or top-tier students over the decades. How to Use the Manual (Without Sabotaging Your Learning)
If you've managed to track down a PDF of the solutions, use it strategically: Verify the Assumptions: Kern often uses specific charts for jHj sub cap H (heat transfer factor) and
(friction factor). If your answer differs from the manual, check if you are reading the same chart.
Reverse Engineer the Logic: Don't just copy the numbers. Look at how the manual handles the tube layout and baffle spacing, as these are the most common areas for errors.
Watch the Units: Kern uses the English Engineering System (BTU, ft, lb, °F). Modern students often struggle with these; the solution manual is vital for seeing how conversion factors like are applied. Where to Find Help
While the original publisher's official manual is rare due to the book's age, you can find high-quality community-solved versions on:
Chegg or CourseHero: For verified step-by-step solutions to specific chapter problems.
Academia.edu / Scribd: Often host the "Hitl" digitized versions of the full manual.
Engineering Forums: Sites like Cheresources.com often have threads dedicated to Kern’s methodologies.
Note: Always ensure you are cross-referencing solutions with the 1950 International Edition or the 1983 McGraw-Hill reprint, as problem numbering can occasionally shift between printings.

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
