a liquid through a pipe will be streamlined or not. by themethod of
dimensions, find the expression for reynold number, if itdepends
upon the velocity (v) of the flow of the liquiddensity()
of the liquid, coefficient of viscosity()of
the liquid and diameter(d) of the pipe.

Awater-filled u-tube manometer is used to measure the pressure inside a tank that contains air. the water level in the u-tube on the side that connects to the tank is 5 ft above the base of the tank. the water level in the other side of the u-tube (which is open to the atmosphere) is 2 ft above the base. determine the pressure within the tank.
