Water is siphoned from the tank shown in the figure below. The water barometer indicates a reading of $$30.2\mathrm{ft}$$. Determine the maximum value of $$h$$ allowed without cavitation occurring. Note that the pressure of the vapor in the closed end of the barometer equals the vapor pressure. Assume $$h_1=5.5\mathrm{ft},d_2=2.5$$ in., $$d_3=5.6$$ in.
