Determine nm, for the model channel.
A river model is to be constructed using Yr = 1/100 and Xr = 1/500, which provides a vertical exaggeration of 5 to 1. The prototype channel has an average depth of 5 m, an average width of 120 m, a discharge of 1500 m3/s, a slope of 0.00032. and a Manning n = 0.021.
Determine the corresponding geometry of the model channel and the required model discharge. Verify that turbulent Row will occur in the model, and calculate both model and prototype Froude numbers (based on the average depth).
Use Matlab to obtain the poles of the system. Is the system stable? Explain.
Figure shows a circuit suitable for op-amp applications. For all transistors β = 100, VBE = 0.7 V, and ro =∞. For inputs grounded and output held at 0 V (by negative feedback) find the collector currents of all transistors. Neglect base currents.
Draw the free-body diagram of the beam which supports the 80-kg load and is supported by the pin at A and a cable which wraps around the pulley at D. Explain the significance of each force on the diagram. (SeeFig)
In the quiescent state, what dc voltage must appear at the output of each of the error amplifiers? At what value of positive vO will QP be supplying all the load current? Repeat for negative vO and QN supplying all the load current.
1. An SCR with a 5V gate trigger level is used with a 12V zener diode, and the capacitor is 0.15uF. What value of R2 will give full control of the power to the load down to zero?
What are the main problems of SMART SMR? Define the components of "Chemical Processing Plant" in MSR? How can SCWR achieve thermal efficiency (>40%) comparing to a PWR's efficiency
Determine, making and justifying assumptions as required, the maximum axial boring rate in units - Describe in detail with the aid of sketches
1. What commands are utilized for the configuration of the Output Compare Timer? How does each affect the time interval of the Output Compare timing?
Using the supplied 3D model of the commercial vehicle available on Moodle and solidworks flowsimulation conduct a CFD analysis to determine the vehicles aerodynamic drag coefficient.
Discuss what is meant by line and load regulation. Should they be high or low if you want a quality power supply?Discuss the differences between a shunt regulator and series regulator and how each works.
