In a nuclear power plant, coolant is a substance:

(a) which cools the hot, spent steam to condense it back to water
(b) which transfers heat from reactor to water in heat exchanger
(c) which is boiled to make steam to turn the turbine
(d) which cools the generator coils to prevent their overheating.

The following six sentences come from a paragraph. The first and the last sentences are given. Choose the order in which the four sentences (PQRS) should appear to complete the paragraph.

S1 : In an ordinary power station we burn fuel to get heat.
S6 : However, instead of getting heat by burning fuel, we get it from the nuclear reactor.
P : In a nuclear power station, we burn water into steam and then use the steam in the same way.
Q : It is from the generator that we get electricity.
R : The steam is then made to turn turbine and through the turbine generator.
S : This heat turns water into steam.

Select the correct sequence.

Q. When water is boiled to

100^{o} C

, it converts into steam which on condensation gives back-water. Here, the heat given out is called ___________________ which is equal to the latent heat of vaporization.

Q. In a particular engine, electricity is used to heat water into steam, which in turn rotates the blades of the turbine. The correct order of energy transformation is:

Q. In a Rankine cycle the steam enters at 200 bar and 400°C to the turbine, condenser pressure is 10 kPa. Power output of cycle is 100 MW. Cooling water is used to cool the steam in condenser.When pump work is not neglected and cooling water enters at 30° C and leaves at 50°C. The mass flow rate of cooling water required is _____kg/s. Data : at 200 bar, 400°C

h = 3400 k J / k g, s = 3.35 k J / k g K

h_{f} = 191.83 k J / k g, h_{g} = 2584.8 k J / k g

s_{δ} = 8.1511 k J / k g K, s_{f g} = 7.5018 k f / k g K, v_{f} = 0.001 m / k g

Specific heat capacity for cooling water =4.18 kJ/kgk

Q. It takes 15 minutes for an electrical kettle to heat a certain quantity of water in grams from

0^{o} C

to boiling point
