hello, I purchased a used pickup camper shell that is made of fiberglass; very smooth and cool with a Euro look. However, the electrical works but is of an abysmal design. Suffice it to say, I ne... Read more »
Bit OT: Surge risk with centrifugal blower
February 26, 2013, 3:37 am
Single stage centrifugal blower, 500KW drive, discharge pressure about 30 KPag, suction more or less atmospheric. There's a distinct pressure dropoff in the curve as the flow gets low, so surge i... Read more »
Boiler steam drum control
February 24, 2013, 12:07 pm
Boiler steam drum control is difficult because of the inverse response. Using adequate control techniques can be of great help. See http://home.arcor.de/janch/20130224-control/page1.html -- Reg... Read more »
