1.There are two .25 m long concentric cylinders in a viscometer. Only the inner cylinder is rotating. THe velocity distribution is given by V(r)=1000r-0.4/r [m/s]. If the diameters of the cylinders are 3 cm and 5 cm, respectively, what is the fluid viscosity if the torque on the inner cylinder is measured to be 0.0026 Nm?

2.A student in the laboratory plans to exert a vacuum in the head space above a surface of water in a closed tank. She plans for the the absolute pressure in the tank to be 10,400 Pa. The temperature in the lab is 20°C. Will water bubble into the vapor phase under these circumstances?
