Marine propulsion is the mechanism or system used to generate thrust to move a ship or boat across water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or engine turning a propeller, or less frequently, in pumpjets, an impeller. Marine engineering is the discipline concerned .

 · Thus, the berthing manoeuver and approach speed is controlled in such a manner that no tug assistance is required. Each of the FCTUs is driven by two electric motors .

 · Paul Evans. . Sep 11, 2017. 10. Pump calculations how to calculate pump speed, head pressure, rpm, volume flow rate, impeller diameter. In this article we learn how to perform pump calculations in both imperial and metric units to assess pumping performance following the change of flow rate, pump speed, head pressure and power.

The coal/ air mixture enters the furnace through a burner nozzle at velocities in excess of the flame speed. Thus, the flame front is held stable at a distance away from the end of the nozzle where the coal/ air mixture velocity has slowed and is equal to the flame speed. From this we see the importance of maintaining burner operating velocities above the minimum specified by the manufacturer ...

Traditional coal mine monitoring systems tend to be wired network systems, which play an important role in coal mine safe production. With continuous enlarging of exploiting areas and extension of depth in coal mine, many lane ways become blind areas, where in there are lots of hidden dangers. Moreover, it is inconvenient to lay cables which are expensive and consume .

binations of motors speeds can provide the same Euclidean movement. Since the system is overdetermined, we show how to compute a set of consistent and optimal motor forces and speeds using the pseudoinverse of coupling matrices. This approach allows us also to perform a consistency check to determine whether a wheel is slipping on the floor or not. We show that it is possible to avoid wheel ...

 · Rotor critical speed: A rotor critical speed exists when a machine's rotating element is the resonant component and its speed matches the natural frequency of the rotor. This is common with centrifugal pumps, gas and steam turbines, and large, twopole electric motors. While the result is similar to structural resonance (high vibration at a certain operating speed), a rotor critical speed is ...

 · A steam train built in 1937 is getting a makeover that will turn it into a "higherspeed" locomotive that runs on biocoal, a coallike fuel made with woody plant material. When finished, the train will be able chug along existing tracks at speeds up to 130 miles per hour without contributing to the greenhouse gas pollution blamed for global warming.
