Right screw propellers and right screw left screw. Yeah. Sir this logics of vendors
propeller is moving that water which comes out its not been the access always it’ll decide
why actually. Oh that is obvious because something is moving in this plane no see there
is a flow here now think of a point here you are pushing at this side then naturally a flow
is being pushed this side slightly. By circulating come outside sir. Yeah see it is it is a
circulation. So, it has got an axial velocity at this side and a velocity this side see any
point is being pushed this side and this side. So, it as effected this way. Resultant will be
Yeah you see the fan here our ceiling fan or any fan you you see the flow is in front,, but
if you take a vector it is not exactly along the straight line you know it will not be
straight line and this is why for a ship if you have a twins screw if you have a this one
this way this one always this way always have. So, that it balance. Yeah always. So, it is
more stable does
