Definition of a turbomachine
We classify as turbomachines all those devices in which energy is transfe
TOPIC T4: PUMPS AND TURBINES
AUTUMN 2013
Objectives
(1) Understand the role of pumps and turbines as energy-conversion devices and use,
appropriately, the terms head, power and efficiency.
(2) Be aware of the main types of pumps and turbines and the disti
HEAT EQUATION EXAMPLES
1. Find the solution to the heat conduction problem:
4ut
=
uxx , 0 x 2, t > 0
u(0, t)
=
0
u(2, t)
=
0
u(x, 0)
=
2 sin
x
2
sin(x) + 4 sin(2x) = f (x)
Solution:
We use separation of variables. Let u(x, t) = X(x)T (t). Then 4ut = ux
