Intel Corp, back in 1979 & early 80's had the absolute finest drafting tables. Electric motor height control, tilt control, glass back lit surface (for layout drafting tape design on mylar D size sheets), swing arms with precision angle degree rotation compass pivots for clear acrylic delineated square angle ruler ... weighed a ton.
My engineering lab cubicle was across from a drafter who loved smoking -pipes & cigars (cigarettes too). That was back when smoking was ok in the workplace.
We used the guy to help in an airflow analysis of a new high-tech "switcher" power supply module. He'd suck on a cigar 'till the cherry was about to drop, then blow into a tube. The eddy turbulence in the airflow identified "dead" spots that the mini fan cfs induced (used clear acrylic enclosure pieces in place of the metal enclosure to view the electronics).
Hi Meyer, here is your answer to the 6th turbine. There is an interesting backstory to this. DWR has been stating that flow has been at maximum through the powerhouse, yet they did not mention that this conflicts with one of the turbines being out of service. The press has noted this discrepancy. The issue becomes "accuracy" in specifics in DWR statements to the press/public, especially in the high state of interest in this spillway crisis.

"Oroville >> During the Oroville Dam spillway crisis, the state Department of Water Resources has frequently said the Hyatt Powerplant was releasing flows at maximum capacity, but technically, that’s impossible."
"Inside the hydroelectric plant are six turbines, machines that produce power by water flowing through a wheel or motor. And one of those turbines has been out of commission since August 2015."
"When asked by this newspaper about DWR’s claim the plant is operating at full capacity, Lauren Bisnett, a department spokeswoman, said the turbine will be reinstalled by December."

"Requests to DWR to interview an employee who could speak about powerplant operation specifics were not granted Wednesday or Thursday this week. Questions continue to be filtered through a public information officer and responded to via email by a PIO."
