Answer / logu

If the pump suction pressure is low the temperature of the
bfw gets reduced and result in cavitation.

Answer / zeeshan ch

water will boil out inside the pump cassing due to very low
pressure zone & high temp of the water itself , boiled
bubble will start to make cavities of compressible fluid ,
resulting in pump status as cavitation

Answer / neeraj dhar

whjerever the suction side flow is lower than the discharge
then it will lead to starvation of the pump and hence lead
to cavitation. thas the reasopn the pipe suction side of
the pump are usually one side larger then the discharge
side of trhe pum;p

Answer / vse

Boiler feed pump minimum suction pressure depends on its operating feed water temperature. At any case the feed water temperature should not over take the saturation point corresponding to its living pressure.

some time there is sudden collapse of pressure in the deaerator due to interlocks / protection , to over come this pump is generally given sufficient NPSH by position.

Answer / siva chukka

If a BFW suction pressure low,boiling point of water decrease,at a temperature water convert into vapour inside casing ,pump head is decreased is called cavitation

Answer / murali

the pumps will trip on protection. cavitation and charling
in discharge end will take place.

Answer / kalaisankar

temprature of the boiler increases due to decrease in
water level in the boiler .

QUANTUM COMPUTING - EXAMPLE 32.3 : A system of linear congruences consists of 3 equations : X ≡ 1 (mod 3), X ≡ 3 (mod 5), X ≡ 4 (mod 6). X has positive values. (a) List the values of these equations from 1 to 35. Then find the minimum value of X. (b)(i) Find the least common multiple (LCM) of b = 3, 5 and 6 where X ≡ a (mod b). (ii) If b - a has the same value of all equations above, then X + (b - a) is divisible by LCM. Find the value of minimum value of X via LCM division.
