A pump used in an open system for pumping water from circulation tank into two wire tanks was worn down and had decreased efficiency. Analysis was done to compare the cost benefit of installing two modifications to the existing system. With an increased demand required only during startup, the conclusion was installing a new smaller pump parallel to the old pump to provide the base load duty. The old pump would only be used during the start up period.
A 30-year-old circulator needs to be replaced in a one-family house. An analysis on the system was done, which concluded that the electronic circulator could be downsized due to the existing hydraulic resistance in the system.
Overview: Replacements are being considered for a cooling water system that currently consists of four volute casing pumps. A cost analysis is done comparing the baseline versus variable pitch propeller pumps and mixed flow pumps with variable inlet guide vanes. Mixed flow pumps have the fastest payback in this application with a payback time of 0.4 years.
To successfully achieve PSC Level 1 certification, it is suggested to follow a structured learning path. This article provides a step-by-step guide to help you prepare effectively.
Overview: August 2024 – Stormwater – Upgrade of the system to accommodate storms and mitigate flooding. If the flooding wasn’t addressed then the problem would continue potentially affecting homes, utilities, and infrastructure. With existing utilities, a stepped-down wet well was utilized to prevent any problems with those utilities.
The Hydraulic Institute (HI) and HI University are excited to announce the launch of their Workforce Development page, now featuring a comprehensive Student and Educators Resource page.
Overview: During a municipal water pump station upgrade, hydraulic engineers got approval to perform field tests to assess the waterhammer (pressure surge) transients. Surge pressure measurements were taken after an induced pump power loss and subsequent check valve slam. They also developed a computer model to see how well available software could simulate the produced transients. This data was gathered to provide guidance to the municipality on future project work.
