Two Yamaha outboard 115 RPM?
I have a Yamaha 115 outboard of two and got a new single 13×21 aluminum strut pushing my zodiac pro 550 lids open …….. 45 mph maximum output at 4,800 rpm is too low for this engine?
WOT for the engine 4500 – 5500 rpm, you can probably run a field Holeshot 19 for better performance and you could probably find better support SOLAS.

Gph Waste

What is your reaction if I say I have designed an engine that is 300% more efficient than the existing engineering
Automobile engine existing (Otto cycle) wastes 75% of thermal energy produced by burning fuel. A small to medium car gets about 25 MPG and the engine is developing about 20 hp, 2.5 GPH cunning consumption at highway speeds. The amount of thermal energy used of 2.5 x 2546 BTU / HP = 51.000 BTU consuming ruse 2.5 GPH to 120,000 BTU per gallon, for a total of 300,000 BTU. Certainly, these are approximations. Some performance figures Otto cycle is as high as 38% to work in pair Max. But most agree that 20-25% is normal. To restate, 50,000 BTU is used while 300,000 are being created. The 250,000 BTU of energy remaining heat is mostly dumped into the environment through cooling system or exhaust.
You are absolutely right that engine performance under normal conditions of typical Otto is about 25% of thermodynamic efficiency. 300% implies a thermal efficiency of 75%. I believe violates the second law of thermodynamics, which states that no heat engine can be more efficient than a Carnot engine operating temperatures between input and output even. Although I have no idea what you have in mind, I am skeptical at this point and would have to convince solid.

Beacon Antenna

How does an automatic direction finder (ADF) work? How small can you do?
ADF has been used for decades as an aid to navigation in aircraft, receives signals from the non-directional beacons. I'm surprised are not on the use of these small robots navigation (eg Roomba). My question is: How does the ADF? (I know there is something called a loop antenna sense …) Also, is there a size limit which makes them unsuitable for small robots?
ADF detect an electric field and magnetic field are perpendicular in space and their amplitudes vary sinusoidally with time. The magnetic field induces a voltage in the coils of the circuit ADF. By measuring the phase difference between the coils of the ADF is able to determine the direction of the beacon. Place the labels in the house and the use of automatic document feeder sailing is expensive and inefficient as the GPS and proximity sensors are available and perform better.

If you look on aluminum blocks allowed in a league of high school?
I found a nice pair of Nike shoes with six tacos tacos soft ground nylon with aluminum nibs. I know how the referee controls always stops before the Games. Is it looking for this kind of peak?
Depends the rules of your local school. Check with your coach.
