In Example VIc.5.1, we derived the efficiency of a Pelton wheel in terms of
V_w
,
V_t
, and
. Use a deflection angle of 165^o,
V_w

=
, and
V_t

=
ωR, as shown in Figure VIc.5.1 and show that the Pelton wheel works most effectively when running at half the speed of the jet of water. Find the maximum efficiency. Comment on the actual Pelton wheel efficiency.
