After looking at a few examples between fluid statics and dynamics I am interested to know where the resultant force would be in the following example.
A straight hose of infinite length containing a pressure flow is pricked by a pin causing a leak- the angle of the hole causes the fluid to be ejected in the opposite direction of the main flow .
Would the resultant force be in front of the hole (Green) as suggested by Fluid dynamics pipe bend control volumes ( if we considered the pin prick an extremely small pipe turning the main fluid flow past 90') or on the opposite side of the hose (Red) as suggested by thrust vector examples in statics.
What confuses me is while there is a flow the hole should only 'see' the static pressure. I imagine both could be correct given the size of hole? Is the difference whether the boundary layer is maintained over the hole?
