1.What is the (a) eulerian acceleration at point x = 1, y = 2, z = 3 for the following velocity field? (b) what is the lagrangian acceleration for the same point?
V = (3x +y)i +(2y z)j- (3y)k
2.In a given experiment it is determined that the pressure change (deltaP) between two points in a pipe is dependent upon the density(p) of the fluid, the diameter(D) of the pipe, and the velocity(V) of the pipe. Determine (a) the number of pi term(s) for this model (b) a suitable set of Pi term(s) for this model
A company has been discharging its waste into a holding pit for a long time. For the last several years, the pit has been full and overflowing into a local river. The waste concentration has been nearly constant at 10 mg/L of the pollutant of inte..
