A water jet with velocity
impinges normal to a moving flat plate with velocity
such that the jet splits equally into two halves as shown in Figure. The jet cross-sectional area is 2 cm
,
is 20 m/s and
is 10 m/s and density of water is 1000 kg/m
. Consider steady flow and neglect weight of the jet, weight of the plate and frictional loss.The absolute value of the force required to keep the plate moving at constant velocity
is ______ N.
