Question

Find: the rate of change of water surface level with a unit of m/s from the given information in the image.

Question 1. Water flows into the top of a conical flask at a constant rate of Q=3.75x10-7 m3/hr. Water drains
out through the round opening of diameter of d37.35mm at the apex of the cone. The flow velocity at the exit
is
v = (2gy)/2
where y is the water level above the exit plane and g is the standard gravity. At the instant of interest, the
water depth H=36.8mm and the corresponding diameter D=26mm.
Q=3.75x107m/hr
D=29.4mm
H=36.8mm
d =7.35mm
v = (2gy)1/2
