Find the flow rate of a fluid of viscosity 1.5 X 10" N-s/m² flowing through a pipe radius 50 cm and length 100m at a pressure differential of 2 x 10 N/m?
A. 0.131 X 105 m/s B. 1.310 x 105 m/s C. 13.100 m/s D. 131.0 X 105 m/s

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
