Answer / logu

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

What would happen if the suction pressure is low in a boiler feed water pump?..

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

What would happen if the suction pressure is low in a boiler feed water pump?..

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

What would happen if the suction pressure is low in a boiler feed water pump?..

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.

What would happen if the suction pressure is low in a boiler feed water pump?..

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.

PROCESS CONTROL - EXAMPLE 6.2 : A stream with volumetric flow rate Q enters a cylindrical tank and a stream with volumetric flow rate q exits the tank. The fluid has a constant heat capacity and density. There is no temperature change or chemical reaction occurring in the tank. Develop a model for determining the height of the tank, h. Let V is the volume, A is the cross sectional area, r is the density, m is the mass, where V and A are for the tank, r and m are for the fluid. The rate of mass of fluid accumulation, dm / dt = (Q - q) r. Prove the model to be dh / dt = (Q - q) / A.

Question 82 - (a) The Hyperion sewage plant in Los Angeles burns 8 million cubic feet of natural gas per day to generate power in United States of America. If 1 metre = 3.28084 feet, then how many cubic metres of such gas is burnt per hour? (b) A reservoir of natural gas produces 50 mole % methane and 50 mole % ethane. At zero degree Celsius and one atmosphere, the density of methane gas is 0.716 g / L and the density of ethane gas is 1.3562 mg / (cubic cm). The molar mass of methane is 16.04 g / mol and molar mass of ethane is 30.07 g / mol. (i) Find the mass % of methane and ethane in the natural gas. (ii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the gases are ideal where final volume of the gas mixture is the sum of volume of the individual gases at constant temperature and pressure. (iii) Find the average density of the natural gas mixture in the reservoir at zero degree Celsius and one atmosphere, by assuming that the final mass of the gas mixture is the sum of mass of the individual gases.

Question 67 – In order to predict the wastewater production, the population number has to be understood. The population data is : 72000 (for year 1961 or P-1961), 85000 (for year 1971 or P-1971), 110500 (for year 1981 or P-1981). (a) Find the average population increase, or [ (P-1981 - P-1971) + (P-1971 - P-1961) ] / 2. (b) Find the average percentage population increase, or [ (P-1981 - P-1971) / P-1971 + (P-1971 - P-1961) / P-1961 ] / (2) X 100. (c) Find the incremental increase or P-1981 - 2 (P-1971) + P-1961. (d) Let Po = P-1981. After 2 decades or n = 2, the population is P-2001. By using arithmetical increase method, find P-2001 = Po + n (Answer for a). (e) By using incremental increase method, find P-2001 = (Answer of d) + n (n + 1) (Answer of c) / 2. (f) By using geometrical increase method, find P-2001 = Po [ 1 + (Answer of b) / 100 ] ^ n where ^ is power sign, or 1 ^ 2 = 1 x 1 = 1.
