Calculate the power delivered to the hydraulic motor in the diagram shown below if the pressure at
A
is
6.8MPa
and the pressure at
B
is
3.4MPa
. The motor inlet is a steel hydraulic tube with
25mm
outside diameter and
1.5mm
wall thickness. The motor outlet tube has an outside diameter of
50mm
and a
2mm
wall thickness. The fluid is oil (
sg=
0.90 ) and the velocity is
1.5(m)/(s)
at point
B
.
