You are assigned the design of a cylindrical, pressurized water tank for a future colony on mars, where the acceleration due to gravity is 3.71 m/s2. the pressure at the surface of the water will be 110 kpa , and the depth of the water will be 13.6 m . the pressure of the air outside the tank, which is elevated above the ground, will be 93.0 kpa .

this is poiselle's equation from fluid mechanic in physics. mech eng

he made 11 calls in one day

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
