Draft fan with draft control for owb5/9/2023 The other factor that affects this relation is the compressibility (K p) of the fluid. The origin of production or consumption of power for fluid machinery has its roots in the fundamental thermodynamic relation:Īs a practical expression, this equation shows that fan efficiency is a function of volume, system pressure, and input power to the fan shaft. The intellectual knowledge base about the power and efficiency is bound to help engineers to properly specify a fan and manufacturers to optimize and design a better fan. Therefore, minimizing input power to the fan will offer direct economic benefit to the plants. The power required to drive mechanical draft fans is viewed as parasitic load. The higher total efficiency is a function of total pressure, which combines static and velocity pressure components, whereas static efficiency only accounts for static component. The efficiency numbers are really a fluid dynamics phenomenon. Motor horsepower requirement for a given fan stays the same. Paradoxically, a calculated higher efficiency does not demand a lower horsepower motor. Fan total efficiency gives higher number while static efficiency calculates a lower number. You can watch it all again and enjoy the banter between the team managers via the embedded video below.It is important to note the difference between these two efficiencies. Sharks (Michelle Dillon): Beth Potter, Kate Waugh, Nicole van der Kaay, Julia Hauser / Hayden Wilde, Tayler Reid, Chase McQueen, Jonas Schomburg. Scorpions (Chris McCormack): Georgia Taylor-Brown, Alissa König, Emma Jeffcoat, Cathia Schär / Vincent Luis, Tyler Mislawchuk, Henri Schoeman, Kenji Nener. Rhinos (Ronnie Schildknecht): Taylor Spivey, Natalie Van Coevorden, Jeanne Lehair, Hanne De Vet / Vasco Vilaça, João Pedro Silva, Sergio Baxter Cabrera, Valentin Wernz. When it all panned out here’s how the final line-ups look (in order of retained / picked), subject of course to potential replacements for any injured athletes.Ĭheetahs (Annie Emmerson): Sophie Coldwell, Rachel Klamer, Verena Steinhauser, Miriam Casillas García / Jonathan Brownlee, Marten Van Riel, Max Stapley, Shachar Sagiv.Įagles (Tim Don): Non Stanford, Sian Rainsley, Sophia Green, Sara Röel / Matthew Hauser, Jamie Riddle, Daniel Dixon, Emil Holm. There was a particular focus on the fans team, with manager Annie Emmerson guided in her Cheetahs picks by input from all those who had signed up to be owners – and they’ll have an important say in tactics and more in the series itself. Photo Credit: Darren Wheeler – That Cameraman / Super League With the first picks out of the way it was down to the snake draft, Don starting off by adding Sian Rainsley while on the men’s side the Bahrain Victorious Scorpions had the #1 selection and Chris McCormack went for Canadian Olympian Tyler Mislawchuk. And this time using first pick, Don put his faith in Aussie Matt Hauser, while Vasco Vilaca – who had a strong and consistent 2021 SLT – heads the Rhinos’ male roster. In the men’s the Eagles and Rhinos were again the two teams not to retain. “Don’t forget the rules are different this year, the short chute goes to the team rather than an individual so the dynamics could be different,” explained Don.ĭon had second pick and brought in Non Stanford, who has had such an incredible month in what’s the last season of her competitive career – winning silver with Wales in the mixed team relay at the Commonwealth Games and then individual gold at the European Championships in Munich. That means he’s missing his two biggest points scorers from 12 months ago – Jess Learmonth, who won three of the four races, is unfortunately injured while men’s title winner Alex Yee is also absent.īut Don elected not to hold onto Taylor Spivey and the American was snapped up straight away by Ronnie Schildknecht as the Rhinos got first pick. Don in the spotlight – again Tim Don heads up the Eagles again īut this year he faced a challenge straight away as only one of his team from last year remained due to a variety of reasons.
