Apitot-static tube is mounted on a 2.5 cm pipe where oil = 860 kg/m3, = 0.0103 kg/m·s) is flowing. the pitot tube is positioned such that the local velocity measured is similar to the mean velocity through the pipe cross section. the pressure difference is measured to be 95.8 pa. find the volumetric flow rate in m3/s.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
