Re: how to define pressure drop formula in a pipe #3 Amit Bhansali Guest Posts: n/a Hi, I am a graduate student from OSU and i would like to know the equation u derived for pressure drop as a function of mass flow rate. Is the equation derived by using Darcy's Weisbach equation?
The shear thinning Ostwald-De waele rheological behavior is selected for the polymer melt. The pressure drop due to the normal stresses and the velocity changes in the flow direction are contributed in the formula. This new formula is examined for the flow of polystyrene and polypropylene melt ...
Modified Bernoulli equation:p1-p2=4 x v2 relates the pressure drop (or gradient) across an obstruction Flow resistance. Poiseuille’s Law:R = 8 x η x L / π x r4 ( η = viscosity, L = length, r = radius). laminar flow only ...
Thus, the pressure difference between the two weather stations is 0.3 Pa/m. This means that for every meter an observer travels, the pressure would increase by 0.3 pascals. Or if the observer moved in the opposite direction, the pressure would drop by 0.3 pascals per meter. View...

The energy balance for the spray renders to a quadratic formula for the drop size as a function, primarily of the liquid velocity. The Sauter mean diameter found using the quadratic formula shows good agreements and physical trends, when compared with experimental observations. This approach is ...
Motivated by the applications, we assume the periodicity of the roughness in the longitudinal direction and that the flow is governed by the prescribed pressure drop between pipe's ends. The goal of the paper is to investigate the effects of the corrugated boundary on the fluid flow by taking...
But when I saw the results Marissa got for the initial test subjects of her Flirting Formula, sheover-the-top impressed me. In fact, she's a complete genius. Her step-by-step formula is all-inclusive…meaning any guy can use it to go from "hello" to the bedroom, a relationship, or...
