A 2 m high sandy fill material was placed loosely at a relative density of 47%. Laboratory studies indicated tht the maximum and minimum void ratios of the fill material are 0.92 and 0.53, respectively. Construction specifications required that the fill be compacted to a relative density of 80%. If Gs = 2.65, determine:
a. Dry unity weight of the fill before and after compaction
b. Final height of the fill after compaction
The entrance to the pipe is reentrant, with ke = 0.9, and the nozzle loss coefficient is 0.045. Find the flow rate and the pressure head at the base of (entrance to) the nozzle.
A water column in a glass tube is used to measure the pressure in a glass pipe. The tube is 1/4 in. in diameter how much of the water column is due to the surface tention effects
Determine the height, h, the water level will rise in the tank before remaining constant. Also, if initially the tank is empty, what amount of time will it take for the water level to rise to h? Be sure to justify all assumptions made.
