An oil with density 950 kg/m3 and kinematic viscosity 2·10-5 m2 /s flows through a horizontal pipe of 30-cm-diameter. Between locations 1 and 2 (which are 100 m apart), a pressure head drop of 8 m is measured. The relative roughness of the pipe is e/D = 0.0002. Find the average velocity [m/s] and the flow rate [m3 /s] in the pipe.

Shari uses the data in the table to predict how her weight on venus would compare with her weight on earth. which is the best prediction shari could make? her weight is greater on venus because venus has less mass. her weight is lower on venus because the acceleration due to gravity is lower. her weight is lower on earth because it is farther from the sun. her weight is greater on venus because venus has a smaller diameter.
