Pressurized Water Reactor:
A Pressurized Water Reactor (PWR) in a power station has a negative temperature coefficient. After it has been operating for a long time at a partial load, explain, using the diagram in Figure Q3, how the operators achieve the increase of power and the events inside the reactor and associated systems which occur in consequence.
Using suitable case studies,
a) Describe the processes and components utilised in a typical natural gas fired combined cycle gas turbine (CCGT) power station,
b) Explain why a CCGT power plant is superior in efficiency to a regular PF coal power plant. Do not submit web based drawings but present your own simple schematic representation(s) of a CCGT installation.
A point is operating simple harmonic motion with a time period 2πs. At its mean position its speed is 0.05 m/s. Calculate its speed when it is at a distance of 0.04 m from the mean
Suppose you sound a 1056-Hz tuning fork at the same time you strike a note on the piano and hear 2 beats/second. You tighten the piano string very slightly and now hear 3 beats/s
In whole analog to the work energy theorem for the translator motion, it might be stated for rotational motion as: Δ W rot = K rot The net rotational work given by the force
Q. A coil of area of cross section 0.5 m 2 among 10 turns is in a plane perpendicular to a magnetic field of 0.2 wb / m 2 . Compute the flux through the coil.
Out of ordinary and extra-ordinary waves, which wave obeys Snell's law?
Q. Show Constant Moment Arm? The simplest case is that of a point mass, and the moment of inertia can be immediately written as I = mR 2 ,
