An open tank contains water at the bottom for a depth of 6 ft and 3 ft of oil ( 0.75) above water. water is discharged from the tank through a 4-inch diameter orifice located 2 ft above the bottom. assuming steady liquid levels and no losses, determine the volume flow rate through the orifice.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
