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.

Atransverse wave is traveling on a string stretched along the horizontal x-axis. the equation for the vertical displacement y of the string is given by y = (1.8 x 10-3)cos[π(13x - 60t)], where all quantities are in si units. what is the maximum speed of a particle of the string

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate
