ENCH 293
FLUID MECHANICS 1
2010
Course Overview
The main part of this course should provide a basic understanding of the behaviour of fluids
and then students should be able to design pipe and pumping systems for single-phase fluids.
There is also an introduction to systems of units, especially the SI system, and to dimensional
analysis. A number of lectures are given on laboratory measurement and report writing. This
course also includes some computing skills and laboratories.
Fluid mechanics (22 KRM)
Units and dimensional analysis (2 KRM)
Report writing (2 JJN)
Error analysis (4 JJN)
Excel, Visio (4 PJJ)

Relation to Other Courses
This is a core chemical engineering course and is a prerequisite of ENCH354.
Course Requirements
There are no requirements to attend lectures but the Anatomy of Engineering sessions, Pump
Applications lab, and measurement lab must be attended.

Last opened 8-Mar-16
5.
The SI system for chemical and process engineering.
6.
Dimensional analysis of the variables used in chemical and process engineering
systems.
7.
Pressure in static systems: pressure, manometers, atmospheric pressure, buoyancy,
acceleration other than gravity.
8.
Dynamic systems:
Bernoulli’s equation: applications of Bernoulli to flow measurement, including pitot
tube, orifice, venturi, weir, spray jet calculations
Other flow meters
Friction
Pipe flow: laminar flow, turbulent flow, velocity profiles, pressure losses in pipes and
fittings, non-circular ducts.
9.
Pumping
Pumps: net positive suction head, complete system
Control of flow with valves and variable speed.
10.
Brief topics
Pipes in series and parallel
Optimal pipe diameter
Compressible flow, drag force, vortex shedding
Laboratories
Excel
Tuesday 23 February and Friday 26 February, 2 pm – 5 pm in the Crypt (Maths and Stats
Building basement). All of the class should attend both afternoons.
Visio: (venue to be advised)
Tuesday 27 April, 2.00 – 3.30 pm. This hands-on session will introduce the use of Visio for
drawing flow sheets. This will be useful for producing diagrams for lab reports over the next
two years and for flow sheets for Design in 2nd and 3rd Pro.
Anatomy of Engineering (E17 & Mechanical Eng Dept.): Each student will be required to
attend two afternoons in the first term to learn about some of the mechanical components
common in chemical and mechanical engineering. There are no marks associated with this but
all students must complete it satisfactorily to obtain a pass in this paper.
Pump Applications Lab (Semi-scale laboratory): Each student will be required to attend one
afternoon lab in the first term. Students work as a group to dismantle and reassemble a pump
and piping network. The pumping rate is then investigated for different discharge pressures.
The objects are to give the students experience of some important plant items, to foster
teamwork and time management skills and to introduce appropriate safety procedures. There
are no marks associated with this but all students must complete it satisfactorily to obtain a
pass in this paper.
Measurement Lab (Level 2 SR Siemon Building): Students investigate the principles of
measurement accuracy by examining the accuracy of basic measuring operations. These
principles are then applied to the calibration of a variable area flow meter. The lectures on
statistics of measurements will be applied in this and later labs.
Fluid pumping and flow measurement (Civil Engineering Fluids Laboratory): There will be
one afternoon for each student consisting of two laboratories to investigate pumping and flow

measurement in the Civil Engineering Fluids Laboratory in the period from 13-22 May.
Students will work as a team in groups of five or six. A group report will be required.
Practical Problems (Level 2 SR Siemon Building): There will be one afternoon for each
student to investigate a number of different fluids problems. No report will be required but an
exam question is very likely to be based on one of the experiments. Students will work in
groups of about three.

Assessment
Assignments Quizzes
An assignment will be given out about 2 weeks before the quiz. A “model” answer will be
made available about 2 days before the quiz. There will be a 30 minute quiz based only on
the assignment. You will need a calculator for these quizzes.
