hydrostatic head and time

hydrostatic head and time

hydrostatic head and time

(OP)
Hi all I have an object (which has valves attached at the bottom) underwater offshore jacket which rotates from a starting point of 17 degrees to 0 , as the object rotates the hydrostatic head on the valves increases over time.

how can I calculate the head increase over a time period (per 10 seconds) until I reach 0 degree final angle ?

initial angle = 17 deg
final angle = 0 deg
initial head = 100m bottom of legs
initial flow rate = 2.7 m3/s per 10 seconds ( at 100m head)

the jacket legs are ballasted with water so as its ballasted the jacket rotates, hence the head is changing as it gets to a vertical position.
