Consider the flow of oil (density = 894 kg/m3 and viscosity = 2.33 kg/m. s) in a 40-cm diameter pipeline at an average velocity of 0.5 m/s. a 300-m-long section of the pipeline passes through icy waters of the lake. disregarding the entrance effects, determine the pumping power required to overcome the pressure losses and to maintain the flow of oil in the pipe

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
