1. It is proposed that the velocity V issuing from a hole in the side of an open tank depends on the density r of the ?uid, the distance H from the surface, and gravity g. What expression relates the variables?
2. Include the viscosity m in the list of variables in Prob. 6.9. Find the expression that relates the variables.

We need to design a piping system that transports 35ft^3/s of water 100ft. The available head is 7ft. The pipe is to be made out of a rough concrete material. Find the necessary diameter for the pipe.
A system including a preheating coil and air washing (directly recalculated spray water) is to be designed to process 10,000 ft^3/min of outdoor air, in barometric pressure of 14.696 psia. Outdoor air is saturated at 30 F enters the preheated, where ..
A pump fitted with 50mm bore ball bearings uses oil whose viscosity ranges from 100cSt at cold pump start-up to 7.5Cst when running at maximum speed and load. If these viscosities are the safe limits for the oil, specify the maximum start-up speed an..
