Question 41
ME-2NAT2 marksNeeds review
For the laminar flow of water over a sphere, the drag coefficient
is defined as
, where
is the drag force,
is the fluid density,
is the fluid velocity and
is the diameter of the sphere. The density of water is 1000 kg/m
. When the diameter of the sphere is 100 mm and the fluid velocity is 2 m/s, the drag coefficient is 0.5. If water now flows over another sphere of diameter 200 mm under dynamically similar conditions, the drag force (in N) on this sphere is ____________.Log in to check the answer
