The water clock (clepsydra) shown in Fig. P3.101 is an ancient device

The water clock (clepsydra) shown in Fig. P3.101 is an ancient device for measuring time by the falling water level in a large glass container. The water slowly drains out through a small hole in the bottom. Determine the approximate shape Rtt of a container of circular cross section required for the water level to fall at a constant rate of 5 cm/hr if the drain hole is 1.5 mm in diameter. What size container (h and RO) permits the clock to run for 24 hr without refilling?
