Hi,
Can anyone help and explain in 'laymans terms' why the power delivered to a turbine is proportional to: -
i) the density of a fluid, and
ii) the cube of the speed of a fluid.
My question application is related to hydro-electric power generation.
Many thanks

Hi,
Can anybody advise on a racking out issue that I have with two SACE E6 breakers? To insert the racking out handle a shutter has to be dropped to allow the handle to be engaged; a standard arrangement in many switches. According to the SACE manual this is achieved by pulling down on a small...
Hi,
I have been asked to investigate noise control methods for waste incinerator stacks. As this is not my field of speciality can anybody give me some ideas or know of any existing solutions to get me started.

Hi,
Knowing virtually nothing about combustion hopefull you guys maybe able to help?
I am working on a dispersion model for NOx emission but I need to work out an effective stack height by using a Briggs equation. But I have no info' on flue gas temperature, gas volume being discharged or flue...
Hi
Can anybody advise on what would cause the internal resistance of a lead/acid 6V 3-cell battery to suddenly drop. The value has gone from 4 ohms down to 0.3 ohms over a period of 2 weeks.
The voltage of the cell has remained constant at 6.58 volts.
This is one battery of 64, all other...
Hi
Could anybody please explain why there is a sign at the top of Yosimite Pass which asks drivers to switch off their cars air conditioning. I am presuming it has something to do with the effect of air prssure at altitude which could damge the A/C unit - but not being fridge minded can...

I have a watermist fire extinguishing system which states 'Protect from freezing'. It has a water filled sensing line charged at about 50 psi, this in turn fires a bank of water filled cylinders at 200 psi.
The installation is in an unheated generator room, so what I would like to know...
Hi
Does anybody know if there is a requirement or guide (in UK)for ventilating transformer rooms? We have 2 x 1MW 11kv/415v ONAN tansformers in their own dedicated rooms, both have ventilation grilles in the entrance doors.
I have been asked if they could be boarded up so to create a 'sealed'...
Normally we tap change our 11000/415v transformers isolated
(as recommended), however due to a high authority supply voltage we had to do a change on a transformer energised but with no load.(load supported via generators) Can anybody advise if this could of had a detrimental affect on the...
Hi
Can anybody give me an indication of what I need to get checked with a heat pump installation. I have a system on a air handling unit whose condenser ices up at the bottom third during the winter months, obviously when we are trying to extract heat from the outside air (typically about 1-2...
I have had a recent situation where I have had a loss of mains and have been running on a single standby generator.
During a programmed switch of 1 of our 4 Silcon UPS systems the generator freq altered to such an extent all UPS modules went onto battery (supply freq out of tolerance). Our...
