An incompressible fluid flows steadily in the entrance region of a circular tube of radius R = 75 mm. The flow rate is Q = 0:1 m3=s. Find the uniform velocity U1 at the entrance. The velocity distribution at a section downstream is u umax = 1− r R 2 Evaluate the maximum velocity at the downstream section. Calculate the pressure drop that would exist in the channel if viscous friction at the walls could be neglected.

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
