ameter of the jet, the actual velocity of the jet, and
the discharge.
3. The liquid in Fig. A has a specific gravity of
3.00. The gage pressure pa = 10 lb per sq in. and
PB is atmospheric. The orifice diameter is 3 in.
and C= C, = 0.95. With h 5 ft, determine
the discharge and the head lost in' the orifice.
4. In problem 3, maintaining the liquid head h
at 5 ft, to what pressure must pa be raised in order
to double the discharge?
