setting Reynold's no: for flow over circular cylinder
 

Hi
I have to simulate flow over circular cylinder at Reynold's no: of 1000. Material to be chosen is water and I have to give incoming velocity u as 1m/s, dia of cylinder is 1m.When i choose water liquid as material, from default density and viscosity the velocity to be given is o.oo1m/s. How can i input this parameters? Thanks in advance.
