Aim To understand the concept of thermodynamics principles
Learning Outcomes On completion of the module, the student should be able to:

Apply the fundamental principles of thermodynamics and
fluid mechanics to energy conversion systems

Demonstrate the performance of thermo-fluid systems
through analytical methods including the use of empirical
relations evolved from non-dimensional numbers

Demonstrate the principles of fluid mechanics and
thermodynamic systems through laboratory experiments
supported with data analysis and interpretations
Online assignment specific to each student on thermodynamics which will be uploaded on
rubrics. Students are required to submit online within the specified deadline. Each Task comprises
of questions assessing theoretical skill, numerical skill and analytical skill. Sample task is provided
below with variables highlighted that are specific to different students.

2. (a) Explain the working principle of working of a gauge used for measuring high pressure in a
boiler
[10 marks]
(b) The water in a tank is pressurized by air, and the pressure is measured by a multifluid
manometer as shown in Figure below. The tank is located on a mountain at an altitude of
1400 m where the atmospheric pressure is 85.6 kPa. Determine the air pressure in the tank
if 1= 0.1m, 2 = 0.15 m, and 3 = 0.05 m. Take the densities of water, oil, and mercury to
be 1000 kg/m3, 850 kg/m3 and 13600 kg/m3 respectively.
[10 marks]
(c) Analyse the change in manometric fluid (oil and mercury) with another fluid on manometric
height h2 and h3 for the manometer given in figure above.
[5 marks]
3.(a) Explain the significance of Reynolds number in fluid flow through a pipe with examples and
draw appropriate diagrams wherever necessary.
[10 marks]
(b) Fluid flows upwards through an inclined conical pipe as per the following specifications:
Type of fluid: Water
Volume flow rate of fluid through the pipe = Q = 0.001 m3/s
Inlet diameter of the pipe = d1 = 0.02 m
Outlet diameter of the pipe = d2 = 0.03m
Difference in height between outlet and inlet = (Z2 – Z1) = 2 m
(i) Draw schematic diagram of the system;
[5 marks]
(ii) Determine difference in pressure between the inlet and outlet. (P1- P2). [10marks]
(c) Analyse the effect of increase in difference in height between outlet and inlet on the difference
in pressure between inlet and outlet.
[5 marks]
