Flow Rate Problem Water is poured into a conical tank at the rate of 2.15 cubic meters per minute. The tank is 8 meters in diameter across the top and 10 meters high. How fast the water level rising when the water stands 3.5 meters deep. Traditional Solution
Volume of water inside the tank
Differentiate both sides with respect to time
When h = 3.5 m
answer Solution by Calculator ShowClick here to show or hide the concept behind this technique MODE → 3:STAT → 3:_+cX2
X 0 10 5
Y 0 π42 π22
AC → 2.15 ÷ 3.5y-caret = 0.3492
answer
To input the 3.5y-caret above, do 3.5 → SHIFT → 1[STAT] → 7:Reg → 6:y-caret
What we just did was actually v = Q / A which is the equivalent of
for this problem.
Problem Water is being poured into a hemispherical bowl of radius 6 inches at the rate of x cubic inches per second. Find x if the water level is rising at 0.1273 inch per second when it is 2 inches deep? Traditional Solution Volume of water inside the bowl
