If you could then perform the same test in a water tunnel, what would the speed of water in the tunnel be? density of water = 1000 kg/m^3, density of air = 1 2 kg/m^3, dynamic viscosity of water = 0 001 pas and dynamic viscosity of air = 1 983 10^-5 pas

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

On a average work day more than work place firs are reorted

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
