Using Pump Performance Curves in PIPE-FLO® to Maximize System Efficiency

A critical step in maximizing the efficiency of a piping system is properly sizing and selecting a pump that best suits the operation. PIPE-FLO® uses individual data points when modeling centrifugal pumps to simulate operation. This approach uses manufacturer pump curves for head, efficiency, and NPSHr to provide an accurate model of pump performance. This month, we will see how test curve performance data is effectively extracted for use in PIPE-FLO®.

Performing a Pump System Assessment on a System with Multiple Loads

Over the last few months, the ESI News Brief has been exploring the intricacies of pump system operation and optimization. We’ve covered the challenges faced when establishing a pump system improvement program, how to develop an Energy Cost Balance Sheet, and how to work through the assessment process for a simple system. For our final installment we will explore how to evaluate a system with multiple loads by breaking it down into circuits with various elements.

Modeling Circuit Setter Balancing Valves Using PIPE-FLO® Professional

Circuit Setters are often used to balance flow rates to heat exchangers in closed loop cooling water systems. Due to the steady state nature of the thermal loads, controlling the flow rates to each user with a fully automated control valve is not economically justifiable. The process of determining the fixed positions of the Circuit Setters to balance the system is iterative and time consuming. However, modeling the system in PIPE-FLO® to determine the valve position of each Circuit Setter is a quick and accurate process.

Engineered Software Employees Support Military Veteran Donation Drive

In April, ESI employee Mark Rosen’s wife, Paige Rosen, brought a donation drive targeting homeless veterans to the ESI office. Paige was part of a five-person team that managed and ran the veteran-centric drive collecting about nine large boxes of supplies for Joint Base Lewis-McChord veterans at the Tacoma Rescue Mission in just one week. Donations included disposable razors, shaving cream, deodorant, shampoo, toothbrushes, toothpaste, travel baby wipes, socks, and snacks. ESI staff sprang to the challenge and filled three of the nine collected donation boxes.

California Utilities Ramp Up Water-Reduction Efforts

Courtesy of Treatment Plant Operator: Utilities across California are increasing efforts to educate customers on new water use regulations as the state enters its fourth consecutive year of drought. Penalties for noncompliance with the new water conservation mandate include fines of up to $10,000 a day. Outreach to connect with utility customers continues to expand as urgency for conservation increases.

Developing a Pump System Assessment with Energy Cost Balance Sheets

Successful implementation of a pump system improvement program starts with everyone involved having a clear understanding of how the pump system operates. In April, we broke down a pump system into the it’s three elements: pump, process, and control elements. Then we discussed how to develop an Energy Cost Balance Sheet for each element. This month we’ll put those techniques to practice by working through the assessment process for a simple system.

PIPE-FLO® Professional Saves Canadian Nickel Mine over $542k in Annual Operating Costs

ESI’s mission when developing and enhancing PIPE-FLO® and PUMP-FLO™ software is to assist clients in realizing energy efficiencies through improved piping system understanding and superior equipment selection. Recently a plant engineer working at a nickel mine in Canada reached out to ESI when the operators proposed an expansion. By using PIPE-FLO® the plant was able to meet the new process requirements, remove eight stages from each vertical turbine, and save over $542k in annual operating costs.

How Do You Use the Expansion Factor to Properly Size Equipment for Compressible Gas Applications?

When sizing equipment for piping systems with compressible gas applications, it is important to account for all factors that would influence the flow rate and pressure drop across the equipment. An under-sized device can result in catastrophic failure that damages the piping system and jeopardizes safety. Understanding how to account properly for gas expansion using the Expansion Factor and applying it to the incompressible fluid flow equation for each device can lower maintenance, operating, and capital costs.
