a) Find the axial and tangential forces acting on a turbine
cascade of blades and then find the values of lift and drag
coefficients CL and CD.
b) A cascade of aerofoils has a pitch of 7.5 cm and a chord of
10 cm. The inlet vel

CONVECTION
6.1 Objectives of convection analysis:
Main purpose of convective heat transfer analysis is to determine:
- flow field
- temperature field in fluid
- heat transfer coefficient, h
How do we determine h ?
Consider the process of convecti

Draw the velocity triangles and sketch the shape of the blades
for the following cases. Find the relative velocity ratio W2/W1 in
each case and compare the value of stage loading coefficient.

Problem 1:
A long, circular aluminium rod attached at one end to the heated wall and
transfers heat through convection to a cold fluid.
(a) If the diameter of the rod is triples, by how much would the rate of heat
removal change?
(b) If a copper rod of th

DOOLITTLES LU DECOMPOSITION
We shall now consider the LU decomposition of a general matrix. The
method we describe is due to Doolittle.
Let A = (a ij ). We seek as in the case of a tridiagonal matrix, an LU decomposition
in which the diagonal entries

DOOLITTLES METHOD WITH ROW INTERCHANGES
We have seen that Doolittle factorization of a matrix A may fail the moment
at stage i we encounter a uii which is zero. This occurrence corresponds to the
occurrence of zero pivot at the ith stage of simple Gau

Resolving Conflict
What is conflict?
Every organization deals with conflict, which can range from mild disagreements to
outright hostility and group disharmony. Still, not all conflict is bad. Some conflict is
healthy for an organization and functions as
