Wilson Model ChemCAD
Total Height is 18.14ft. This comes from the HLL (high liquid level) + m
Point A: x.2,y.2 (the compositions of the liquid and vapor streams leaving stage 2)
Point B: x.4, y.5 (liquid coming off stage 4 and vapor coming off stage 5)
To find the temperature of stage 2 I would use K (y2/x

Chemical Engineering 374 Homework 25 We want to pump water at 60F from one reservoir to another 120 ft higher through 1500 ft of 16-in-ID pipe with friction factor f=.030. We have two 32-inch pumps from the family of pump curves shown below. Should we use
Homework 18 Special Problem Water at 20 oC flows through three horizontal cast-iron pipelines that have the following properties: Pipeline Length (m) Diameter (m) Fittings K 1 800 0.12 25.4 2 600 0.08 19.1 3 900 0.10 30.6 (a) Find the flow rate for the ca
Homework 13 Problem 1. Pressure drop per unit length in a pipe is a function of the pipe diameter, density, viscosity, and average velocity. Use the PI method to find the dimensionless groups. Your method can result in any consistent set of PI's, but you
Solving the 1D unsteady momentum equation: du/dt = mu/rho*d2u/dx^2 dPdx/rho Use the forward Euler (time) central difference (space): first order in time, second order in space Unstable for "d" = dt*mu/rho/dx/dx > 0.5 CHANGE THE YELLOW BOXES Index Position

ChE 374Lecture 32Turbines
Pumps add mechanical Energy to increase the fluid head. Turbines EXTRACT mechanical energy at the expense of fluid head (decreased pressure). Turbine types: Hydraulic, wind, steam, gas. Typically more efficient than pumps (large
ChE 374Lecture 31Pump Scaling
Series and parallel pumps: Series Goal: provide greater head for the same flow rate Htot = H1 + H2 Pump performance curve is the vertical sum of each individual pump bhptot = bkp1 + bkp2 at the operating point Issues: If the
ChE 374~Lecture 29External FlowsDrag
External ows are flows over objects: cars, wings, buildings, etc.
Objective: Understand and compute drag forces on objects.
Concepts: Flow separation, Lift, Drag, Drag Coefcient, Laminar/ Turbulent.
Drag is the forc
