Temperature is in K. I found 5000 estimate, but used slightly different numbers to get me 230t thrust to match initial Raptor spec.
propellant rate [kg/s], Ve [m/s], Temp [K]
I checked launch video again and in first 3 sec there is no motion, so time to clear 146m tower is about 7s. with...
I did some quick calculations, assuming 650 kg/s of MO is supplemented with H20 up to 1400 kg/s
Looks like 40% of thrust is possible with 2:1 water to MO ratio.
Unlikely such a gain is possible without Raptor redesign given 3 times mass flow increase.
In turbojet engines water injection permits large fuel increase to gain extra thrust by lowering temperature and preserving engine from damage. See more discussion here: aviation. The gain of thrust is paid by much lower overall efficiency as 4 times more fuel is burned to gain 64% thrust...
Water injection could increase jet engine thrust by as much as 64% by increasing mass flow and somehow decreasing exhaust speed end temperature. All those effects should be very welcomed for initial 10s of Starship launch, till it clears the tower. How feasible is a contraption that could inject...
Here is a concept suggesting reactionless drive:
Setup: A light pulse of wavelength l0 bouncing between 2 mirrors one on the left - ML and one on the right - MR. Each mirror oscillates perpendicularly to light travel direction attaining relativistic speeds vl, vr. Light pulse is timed so it...
As a first step in Venus terraforming I suggest to blow out thick atmosphere, mainly CO2. This could be accomplished with thermonuclear explosion an order of magnitude stronger then one that the have been experienced on earth. The idea is to produce local heat source of the range 5*10^8K to...
Thats about summarizes all the attempts to circumvent speed of light while building communication device. Glad to learn that, since I start to be afraid of retrocausality.
another clarification:
Is this behavior affected by what is happening to the entangled partner ? I mean, if entanglement is destroyed at some point in time is photon regaining its single particle interference skills ?
DrChinese and Cthugha is lack of interference of entangled photons inherent phenomenon or it results from technological limitations of generating apparatus ?
After all, you could see interference fringes from a candle if slits are far enough from source and one use sensitive detector...
assembly i describes has double slit (not present in original quantum eraser) so there is no reason to expect lack of interference if photons or their entanglement partners wave function have not collapsed yet. But if one side has been measured then interference seems to disappear ...
Let say we take each of the entangled photons and send one of them to receiver and one to transmitter located light years away. On receiver side photon is passing through double slit and hitting the screen. On transmitter side there is movable light stop placed at the same optical distance from...
