Steady flow occurs, when the

The Stoke's stream function applies to the

In case of turbulent flow of a Newtonion fluid in a straight pipe, the maximum velocity is equal to (where, Vavg = average fluid velocity)

For Laminar flow through a packed bed, the pressure drop is proportional to (Vs is the superficial liquid velocity and Dp is the particle diameter)

The equation given below is called the __________ . $${{\text{f}}^{ - 0.5}} = 4.07\,{\log _{\text{e}}}{\left( {{{\text{N}}_{{\text{Re}}}}\sqrt {\text{f}} } \right)^{ - 0.6}}$$

The fluid velocity varies as the square root of the cylindrical pipe diameter in case of steady state laminar flow at constant pressure drop fo __________ fluid.

Permanent loss in a venturimeter is about __________ percent of the pressure drop in theupstream cone.

The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is $$\Delta {\text{p}}.$$ If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be

The simple pitot tube measures the __________ pressure.
