    Lenght of exhaust pipe

    If you ask this question in the 'Engine & fuel Engineering' forum, I'm sure someone will be able to help you.

    Bearings

    There is a forum for you already - called 'Bearing Design, Manufacture and Maintenance'! (Maybe you've found it)

    sonic flow in nozzle

    If the API derivation was for lb/hr their constant would be 0.1443 * 3600 = 519.48 !!

    KIVA code for Combustion modelling

    You might like to do some research - before you spend any money - on what hardware you actually need. This depends, obviously, on what software you are going to be using, but it does seem to me that if you really are intending to operate at the Cray level, you don't need any help from anybody...

    SPECIFIC HEAT OF HYDROGEN

    What is the temperature range you are interested in? (Is the hydrogen gas or liquid?)

    Cost of bulk oxygen plant

    Thankss, DC, for your prompt reply. The energy cost of separating oxygen is small, about 0.25 kWh/kg, I believe - a small fraction of the energy released by combustion. The reasons for using pure(ish) oxygen are to avoid any problem with NOX formation in the combustor AND the need to separate...

    Cost of bulk oxygen plant

    One way of making a dent in atmospheric CO2 levels is to capture the CO2 produced in thermal electricity generating plant and pump it down oil/gas wells or to the bottom of the ocean. A feasible method of capture is to burn the fuel in the presence of oxygen (not air) and a diluent, either...

    Distance between on- and off- ramps

    Thanks for your helpful message. I'm in the UK but thanks to Google I found the NY DOT site in seconds, and its highway design manual told me more than I wanted to know ! (Does each state have its own manual ? Are they different ?)

    Can fluid pressure be overcome

    If you seal the top of the silo with a lid capable of withstanding vacuum and then pump the air out above the surface of the water, the pressure you need to push air into your barrel at the bottm of the silo WILL decrease by the amount of suction you generate under the lid (maximum improvement...

    Vacuum Cleaner Attachment Design

    Jason, I'm fairly sure that you will not be able to suck air quickly enough through an orifice that large (11 inches by 0.5 inches) to pick up anything heavier than (perhaps) confetti. Look at the orifice at the business end of your dustbuster as it came from the store. Anything much larger...

    Distance between on- and off- ramps

    I'd be grateful for a link to information (e.g. highway Dept. design rules) about recommmended minimum distance along a freeway from an on-ramp to the next off-ramp.
