Reynold’s number (r), a dimensionless quantity determines the condition for laminar flow of a viscous liquid through a pipe. r is a function of density p of the liquid, its speed of flow v and coefficient of viscosity n . r is directly proportional to diameter d of the tube through which it flows. show that r is proportional to pvd/n

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.
