What else can I help you with?
A receiver requires 10nW as input power if all the system losses add up to 50dB then how much power is required from the source?
here, the power required by the receiver is the output power and that required from the source is input power. Gain in dB=10 log(output power/input power) we have, loss in dB = -gain in dB = 10 log(input power/output power) or, 50 = 10 log(input power/10nW) or, anti-log(5) = input power/10 nW so the power required from the source is antilog(5)*10nW = 1 mW
How much power is required for a ten story building?
12 of them
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
The three factors required to determine power requirements for a task are?
The answer is Force, Distance, and Time.
What amount of electricity is needed to power a city?
Depends on the size, to power a city of one million inhabitants is required average electric power of 475 megawatt-hours (MWh)
How does a pilot control a helicopter?
A helicopter is controlled with a joystick, which usually lies between the feet. Power is usually set at one point in flight and left until landing is necessary.
What is a pilot boat?
Pilot boat is a boat carrying a pilot. Pilot is a local captain who boards a vessel ( ship ) to navigate it into a habour or port. A boat carrying a pilot for embarkation on a ship or after disembarkation from a ship is a pilot boat. Under COLREGS it is required to show a white over red all round lights for identification. No special privledges for for this boat under colregs. A pilot boat not carrying a pilot is not considered a pilot boat but a normal power driven vessl.
Did anyone invent the solar helicopter?
Igor Sikorski invented the first helicopter. The inventor designed the helicopter to use solar power as a means of energy.
What is a turbine helicopter?
A helicopter with a jet engine. The engine is adapted to give power to a transmission, rather than thrust.
What happen if he blades stop spinning on a helicopter when it is in the sky?
If the rotor blades of a helicopter stop spinning while in the sky, the helicopter will begin to lose lift and descend rapidly. It would enter a condition known as autorotation, where the helicopter can glide down safely by allowing the rotor blades to spin freely due to the downward motion of the aircraft. However, without engine power, the pilot would need to manage the descent carefully to achieve a safe landing. If not handled properly, it could lead to a crash.
Is there a flight procedure for take off of a helicopter above its certified OGE altitude?
Ask Filipone: Assume that the helicopter has landing gear. Start running on the ground until you reach a reasonable speed. Then you take off with a forward flight speed. This helps you, because the power required is lower that the power for vertical flight. Look at a typical power curve versus speed. Please circulate answer. Antonio Filippone
What is the circumference of a helicopter propeller?
The circumference of a helicopter propeller can vary depending on the size and type of helicopter. Generally, the circumference of a helicopter propeller can range from a few feet to several feet in length.
Why fixed wing aircraft need less power full engine to fly then a helicopter?
Helicopter 'lift' is provided by the rotor blades creating lift. A fixed wing aircraft creates lift by moving the aircraft forward to create a pressure differential between the upper and lower surfaces of the wing. Power required from the engine to a propeller to move the aircraft forward (on wheels) to gain sufficient speed is much less than lifting the 'dead' weight of a helicopter.
How do you land a RC helicopter?
You slowly decrease power by lowering the throttle. Make sure the Helicopter is coming to the ground at a slow pace and gently. Do not rush, because this could cause a faulty landing. Lower the Helicopter to the ground and when it touches, you can cut the power.
How might an aeroplane fly like a helicopter?
It flies Like an Airplane and Hovers Like a Helicopter... or if the engine has enough power to it, and the pilot brings it up to a 90 degree climb, lets it slow down, then adjusts the throttle to hover the plane...
How much does it cost to build a helicopter engine?
Almost the same as the other similar aircraft engines. And depends on the size of the helicopter, consequently to the power of the engine.
How can you use it a sentence conceptualize?
Genesis conceptualized a helicopter, a tank, and the solar power.
