313310 Thermal Engineering(TE) Lab Manual Answers PDF
MSBTE 313310 Thermal Engineering(TE) Lab Manual Answers K Scheme 3rd Semester, Thermal Engineering is a vital subject in Mechanical Engineering that deals with the study of heat, energy conversion, and thermal systems. Understanding this subject practically is as important as theory, and that is where the lab manual plays a crucial role.
Thermal Engineering in the MSBTE Diploma (Mechanical 3rd
Semester, K Scheme) syllabus focuses on the practical study of heat
engines, boilers, compressors, IC engines, and refrigeration systems. The
experiments help students to understand how thermal energy is converted into
useful work and how different machines perform under various operating
conditions.

313310 TE Lab Manual Answers:
- What
is thermal engineering?
Thermal engineering is the study of heat transfer, energy conversion, and thermal machines. - What
is a heat engine?
A heat engine is a device that converts heat energy into mechanical work. - Give
examples of heat engines.
Petrol engine, diesel engine, steam engine, and gas turbine. - What
is the difference between 2-stroke and 4-stroke engine?
A 2-stroke engine completes one power cycle in 2 strokes, while a 4-stroke engine requires 4 strokes. - What
is indicated power?
Indicated power is the power developed inside the engine cylinder. - What
is brake power?
Brake power is the useful power available at the engine shaft. - What
is mechanical efficiency?
Mechanical efficiency = (Brake power / Indicated power) × 100. - What
is thermal efficiency?
Thermal efficiency = (Work output / Heat input) × 100. - What
is a boiler?
A boiler is a closed vessel used to generate steam by transferring heat to water. - What
is the difference between fire tube and water tube boiler?
In fire tube boilers, hot gases pass through tubes. In water tube boilers, water flows through tubes. - What
is a Cochran boiler?
A Cochran boiler is a vertical fire tube boiler used for small power requirements. - What
is a Babcock and Wilcox boiler?
It is a water tube boiler suitable for high pressure and high steam capacity. - What
is a steam turbine?
A steam turbine is a rotary machine that converts steam energy into mechanical energy. - Differentiate
between impulse and reaction turbine.
Impulse turbine uses kinetic energy of steam, while reaction turbine uses both kinetic and pressure energy. - What
is refrigeration?
Refrigeration is the process of removing heat from a low-temperature body and rejecting it to a high-temperature body. - What
is COP in refrigeration?
Coefficient of Performance = (Refrigerating effect / Work input). - What
is the difference between refrigeration and air conditioning?
Refrigeration is cooling of space or substance, while air conditioning controls temperature, humidity, and air purity. - What
is a compressor?
A compressor is a mechanical device that increases the pressure of air or gas. - What
is the function of a carburetor?
A carburetor mixes air and fuel in proper ratio for combustion in a petrol engine. - What
is ignition delay in diesel engine?
The time between fuel injection and actual combustion in a diesel engine. - What
is knocking in IC engines?
Knocking is abnormal combustion causing noise and damage in engines. - What
is scavenging?
Scavenging is the process of removing burnt gases from the cylinder and filling it with fresh charge. - What
is superheating of steam?
Superheating is heating of steam above its saturation temperature at constant pressure. - What
is calorific value of fuel?
The amount of heat produced by complete combustion of a unit mass of fuel. - What
is a condenser?
A condenser is a device used to condense steam into water. - What
is entropy?
Entropy is the measure of disorder or randomness in a system. - What
is specific fuel consumption (SFC)?
SFC = Fuel consumed per unit power per unit time. - What
is the function of intercooling in a compressor?
Intercooling reduces the temperature of air between stages to save power. - What
is the function of cooling system in IC engine?
It removes excess heat from the engine to prevent overheating. - What
is a gas turbine?
A gas turbine is a rotary engine that converts energy of hot gases into mechanical work.
