A tidal energy system has an average tidal range of 5 m and a basin area of 21.5km^2. The system is designed to generate power during both incoming and outgoing tides. The seawater density 1025kg/m^3, and the tidal period is about 12.5 hours.(a)Determine the maximum average tidal power at the site?(b). If the overall efficiency of the plant is 30%, find the annual electric energy produced?
A six pole,60 Hz synchronous motor is connected to an infinit bus of 15 KV through a transmission line.The synchronous reactance of the motor is 5 ohm ,and the inductive reactive reactance of the transmission line is 2 ohm
(a) If the primary coil, Nsubp has 500 turns and Vsub2=240V than, how many turns does the secondary coil have (b) If the turns ratio is 5, and Vsub2=240V, than, what is the current flowing through both coils
Design a 4-bit synchronous up/down counter using T flip-flops. The circuit has one input up' /down such that input 0 means count up and input 1 means count down. up' is "up" with a bar over it
Explain the relationship between the input and the output ac signals for a n-channel BJT voltage-divider bias. What components/parameters does the voltage gain depends on
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any basic circuit element. State the values of all circuit elements (in ohms, farads, etc).
Scientists have proposed using the radiation pressure of sunlight for travel to other planets in the Solar System. If the intensity of the electromagnetic radiation produced by the Sun is about 1.4 kW/m2 near the Earth
The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work).
A 12 bit ADC with Vref of 5V is used to digitize a sinusoidal signal a quiescent value of 2.5V and a p-p amplitude that is restricted to 1.5V p-p. What is the ENOB of this ADC with this input signal due to quantization noise
A collimated light beam from a helium-neon laser at 632.8 nm wavelength impinges on a dielectric film of refractive index of 2.0 at an angle of 75 degrees to normal, with a polarization at 45 degrees to the plane of incidence.
