Jane,
no, I want you to answer my questions. PBL |
you single Jay?:hmm:

Jane,

I posted this once, then pulled it because Jane Doh is almost certainly an anti-sciolist, but for those who are genuinely interested, the speed of sound expressed in EAS is independent of temperature. You only need to know pressure altitude and then multiply by Mach Number to get the flight EAS.
Values: Press.Alt Speed of sound 65000 ft - 156.02 kts EAS 70000 ft - 138.35 kts EAS 75000 ft - 122.69 kts EAS 80000 ft - 108.8 kts EAS |

Thanks for your post, I was interested as to the correct answer.:ok: |
anti-sciolist
If that means does not read, consider and properly respond to what is sent to them then I agree.

Sciolist means an amateur, right? Pressure altitude means the pressure at a given altitude? |

How do we get from the pressure altitudes that you have quoted, to the EAS values by multiplying by Mach 1? |
If I am reading you correctly you are saying that the EAS in the right hand column is the local speed of sound (Mach 1) at the pressure altitude in the left hand column. How do we get from the pressure altitudes that you have quoted, to the EAS values by multiplying by Mach 1? I didn't say multiply by Mach 1, I said multiply by Mach Number; i.e. the EAS at say Mach 1.4 at 65000 ft would be 218.4 kts Perhaps I should have written "you only need to know the pressure altitude to get the speed of sound in kts EAS and then multiply that by Mach Number to get the flight EAS" CliveL http://images.ibsrv.net/ibsrv/res/sr...ser_online.gif http://images.ibsrv.net/ibsrv/res/sr...ons/report.gif http://images.ibsrv.net/ibsrv/res/sr...eply_small.gif |
Sorry Clive,
When I read you post I thought that you were saying "Multiply the pressure altitude by the mach number and you get the EAS at that mach number". For one fleeting moment I thought that this was going to be one of those really magical moments like the day I was first introduced to Calulus all those decades ago. Now I see that what you were really saying was "If you have a table of pressure altitudes against the EAS for local speed of sound, then just multiply this EAS by any given mach number and you will get the EAS for that mach number at that pressure altitude". |

I'm sorry that I didn't properly read your messages. I should have paid more attention. BTW: In regards to the video that Pugilistic Animus showed, you're a very good narrator Pugilistic Animus & John Farley Fascinating video. I never knew the Harrier used reaction control systems |

PBL, who on earth do you think would have any interest in building such an incredibly sophisticated system as Jane-Doh ... and come up with the idea to of all things test it on an aviation forum? I can see only one logical conclusion: Jane-Doh is Skynet!

What are the formulae for specific heat at constant pressure and specific heat at constant volume? I'm not entirely sure what you mean by specific heat, are you attempting to apply pV=nRT to this or something else? |

your my kinda women Jay....always asking questions...most don't ask..you single?

you single? |
