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

The Legacy of D.Q. Kern’s "Process Heat Transfer"
Before Kern's book, heat transfer was often treated as a theoretical branch of physics. Kern's contribution was the first to bridge the gap between theory and industrial application, specifically for chemical engineers. His systematic approach accounts for real-world variables that many modern textbooks simplify, such as:
Fouling Factors: The accumulation of unwanted material on heat transfer surfaces over time.
Pressure Drop Calculations: Essential for sizing pumps and ensuring fluid can actually move through the exchanger.
Shell-and-Tube Geometry: Detailed methods for baffle spacing, tube pitch, and shell-side fluid flow. Understanding the "HITL" Designation
The term HITL in the search query often refers to "Human-In-The-Loop." In modern engineering education, this typically signifies a pedagogical approach where a student (the human) must actively engage with a model or simulation to validate results, rather than relying on a fully automated "black box" solution. For the Kern manual, this emphasizes that the solutions are not just numerical answers but guided step-by-step methodologies requiring engineering judgment. Key Components of the Solution Manual
A high-quality solution manual for Kern's text typically provides detailed work for the following topics: Energy Balances: Establishing the heat duty (
) using the mass flow rate, specific heat, and temperature change of the fluids.
LMTD Calculations: Determining the Log Mean Temperature Difference, including the Ftcap F sub t correction factor for multi-pass exchangers.
Coefficient Estimation: Calculating the individual film coefficients (
) for both the tube and shell sides using dimensionless numbers like Reynolds and Prandtl. Overall Heat Transfer Coefficient (
): Synthesizing individual resistances (convection, conduction, and fouling) into a single design parameter. Where to Find the Manual

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
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
