1 T V l n = 5 dimensional parameters
2 Select primary dimensions M ,L,and t.
r = 3 primary dimensions
4 Select repeating parameters ,V ,and l. m = r = 3
5 Then n m = 2 dimensionless groups will result.
ME203 Heat and Flow 2
Tutorial sheet #1 Intro/Review
The volume flow rate, Q, through a pipe containing a slowly moving liquid is
R 4 P
given by the following equation: Q =
, where R is the radius of the pipe,
P is the pressure drop along the pipe,
