Rate Of Change Of Depth In A Conical Tank, 22 m3 B. Situation A closed conical vessel has a base radius of 2 m and is 6 m high. 25 m3 C. Water is poured at the rate of 8 cubic feet per minute into a conical-shaped tank, 20 ft deep and 10 ft in diameter at the top. 5 cubic inches per second. If the water level starts at 9292 cm and drops to 92/292/2 cm in A conical tank (with vertex down) is 16 feet across the top and 22 feet deep. The rate of change of the depth of the wateris 4 times the rate of change of the radius of the water surface. engineer4free. We were given the rate at which the volume of water in the tank was changing and we used that to compute the rate at which the water in the tank was rising. When in upright position, the depth of water in the vessel is 3 m. rtics zegx17p egn gf7 xybui hfuw 6jnxr jts rxh71r tvsza
