Liquid methyl ethyl ketone (mek) flows through a pipe with an inner diameter of 2.067 inches at an average velocity of 0.48 ft/s. at the fluid temperature of 20°c the density of liquid mek is 0.805 g/cm3 and the viscosity is 0.43 centipoise [1 cp 1: 00 103 kg/ m s]. without using a calculator, determine whether the flow is laminar or turbulent. show your calculations.

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
