How is thermal energy transferred through water?
There are three different modes of transfer of heat CONDUCTION: Especially in metals. Thermal energy here is considered to be the lattice vibrations in the metal. So, by successive vibrations, as we heat one end of the rod the other end gets hot. CONVECTION: In this process, heat is considered in the form of kinetic energy of the molecules. So as we heat the bottom of a vessel containing water those molecules at the bottom gain kinetic energy and shoot up to reach the top. Thus the thermal energy is transferred due to the movement of the molecules. Interesting information. Water is good convector but a very bad conductor! RADIATION: Here thermal energy is transported neither by the lattice vibrations nor by the movement of molecules It passes even through free space in the form of electromagnetic waves i.e. in the form of electric and magnetic energy.
What is screw race effect on ship?
Screw race is the additional flow past the rudder that is cause by the propeller turning at a faster speed than the vessel is moving through the water. This allows a vessel to turn more effectively when this is occuring. Ex. A vessel is stopped and the engines are put ahead while the rudder is hard over. The flow over the rudder will turn the vessel.
How long does powered nuclear ships fuel last?
This information is classified in most cases; however, it is safe to say that a typical nuclear ship has enough fuel to last for many many years. It varies depending on the country of manufacture, and the type of nuclear vessel you're referring to.
What is the effect of dry steam entry in to a wet steam filled vessel whether it promotes condensation in the vessel?
The effect of dry steam entry into a wet steam filled vessel will promote condensation in the vessel. However, it will be less wet because of the dry steam.
What are the main factors that contribute to total peripheral resistance?
Blood vessel diameter,blood viscosity and total vessel length
What is the name of A vessel powered by 1 or more engines using thermal energy?
All gliders are powered by one engine(the sun) and use the thermal energy from that engine to maintain flight. They need assistance to get into the air usually, but can stay up all day.
Did the Titanic have a double hull?
No - it was a vessel powered by diesel-engines.
What is a thermal cup?
a thermal cup is an insulated drinking vessel.
What was the first nuclear powered vessel?
The first nuclear powered submarine was the USS Nautilus.
When a sailboat overtakes a power boat which vessel is the stand -on vessel?
When one boat overtakes another, the overtaking vessel is considered the give-way vessel no matter what it's powered by.
When a sailboat overtakes a power boat which vessel is the stand-on vessel?
When one boat overtakes another, the overtaking vessel is considered the give-way vessel no matter what it's powered by.
What is Vessel Cold Move?
When vessel's Engines failed and she moved by tugs, it called vesse's cold move
The term sailing ship refers to what kind of vessel?
A sailing ship is referred to nowadays as any large wind-powered vessel. Generally you will find that these ships are completely powered by a series of masts and sales.
When a sailboat overtakes a power boat which vessel is the stand on?
When one boat overtakes another, the overtaking vessel is considered the give-way vessel no matter what it's powered by.
How does a steering wheel on a boat steer the boat?
The steering wheel on an outboard powered vessel, turns the engine port and starboard, (left and right) to steer the craft. On an inboard/outboard powered vessel, the outdrive unit is steered in the desired direction of travel. For an straight inboard powered vessel, the helm is connected to a rudder which when turned, steers the craft port or starboard.
What is powered by a nuclear reactor?
A steam turbine/generating unit, or a naval vessel
What type of water vessel are personal water craft considered?
class A
