Light no. 10 oil is heated from 95°f to 105°f in a 0.6 in inside diameter tube. the average velocity of the oil is 2.0 ft/sec. the viscosity of the oil at 100°f is 45 centistokes (cs). what is the reynolds number inside the tube?

Estimate the kinetic energy of the neptune with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the neptune is a uniform sphere with mass = 1.0×1026 kg , radius = 2.5×1010 m , rotation period 16.1 h , orbital period 6.01×104 d and is 4.6×109 km from the sun.]
