A sheet pile wall has been installed partially through a silty sand layer. Assume the sheet pile is 12m long and penetrates 6m into the silty sand layer of thickness 12m. For this condition a) Draw the flow net using 3 (max 4) flow channels. The flow net should be completely symmetrical about the bottom of the sheet pile b) If the water height on the upstream side is 5m and on the downstream side 1m, compute the amount of water flowing under the sheet pile per meter of wall if the coefficient of permeability is 3.1x10-4 cm/sec. c) Compute the maximum hydraulic gradient at the downstream side of the sheet pile

i think the answer would be reserve.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles

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
