I would like to have two worksheets, I'll call them A and B, within a workbook. I would like worksheet B to display only certain data or cells from worksheet A. The goal is to be able to use worksheet A for my estimating work, and have only those values which I want the customer to see...
When a blower in a vacuum application also has piping on the discharge side, resulting in positive pressure, how do you determine the flow, temp rise, input power etc from the performance curves? Most blower vendors' literature includes separate vacuum and pressure curves for flow, temp rise...
What are the most recommended pump types for discharging liquid from a liquid knockout tank that is under vacuum? Example, a knockout tank under 27" Hg vacuum, and a pump is desired to operate @ 10 psig discharge pressure while the tank remains under vacuum. Normally I have seen a PD pump...
I have a roots blower at a remote site. The blower was supplied as part of a complete package by the vendor, including belt-drive (speed increase set-up) and motor and accesories. Based on our current process/ambient presures and temperatures, and the blower RPM, the vendor's modelling program...
Can someone verify that I am calculating my scfm to acfm conversion correctly?
Problem: The goal is to achieve 35 scfm at 100 psig. The conditions are 6500 ft elevation (assume 11.56 psi absolute atmospheric pressure) and I am assuming 80° F as the compressors discharge temperature based on...
What do you use for the dimensionless friction factor (f) for PVC pipe when calculating frictional losses for air flow? Are there any charts out there with friction factors for different sizes of clean, new SCH 40 PVC pipe? I know there is little data for air flow in PVC pipe because it is...
Looking for advice on a good text for mechanical technologist new to thermodynamics. Would like something that starts with basics of heat transfer and progresses to intermediate (basic design of heat exchangers etc.). Have Applied Thermodyanmics (Eastop & McKonkey, 5th edition) but would like...
Looking for good resource/text for theory, calcs and sample problems. Problem is sizing and designing shell and tube, plate, and other types of heat exchangers for preheating waste gas upstream of thermal oxidizer using the oxidizer off-gas. Thanks.
