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 150-kg roller-coaster car climbs to the top of a 91-m-high hill. How much work is completed against gravity as the car is lifted to the top of the hill?
Explain header and stretcher. Header A brick laid with its length perpendicular to the direction of wall is known as a header. A course of bricks in which all the bricks a
There is a maximum depth at which a diver can breathe through snorkel tube because as the depth increases, so does the pressure difference, tending to collapse the diver's lungs. S
Obtain Relativistic expression for the kinetic energy of the particle. Derive mass energy relation. Show that total energy E and momentum P are related, where m is rest mass and
Two forces have magnitudes of 11 newtons and 5 newtons. The magnitude of their sum could NOT be equal to which of the following values? a) 16 newtons b) 5 newtons b)
Direction of Acceleration and Velocity Knowing the size of a distance or speed is frequently meaningful for creating comparisons. For example, for some reasons it may be enough
Resistance in Series: In such a combination the resistors give a single path to the passage of current and similar current passes by each of the resistors.
VELOCITY: The time rate of change of displacement of a body is known as velocity. It is represented by V ?.
Show that the Nusselt number for a sphere in a quiescent fluid is 2. Hint: Write the thermal resistance for the outer surface of the sphere in terms as both conductive and conve
derive an expression for density of states and hence deduce an expression for carrier concentration of metals
