Answer / raj kumar

mixd bed has the mixture of resin as strong base anion and
strong acid cation. so due to presence of acid cation ph is
reduced

Answer / amrut maisuria

why water passes first in SAC and then SBA ?

Answer / a n jha

it seems ratio of cation and anion resin quantity are not in
balance.if the cation resin is more than anion resin,ph of
dm water shall go less than 7 i.e. it will be acidic in nature.

Answer / nitesh raghuwanshi

When water passed from SBA AND COMES IN MB , MB CATCH SOME MORE ION THAT WHY WE GET LESS PH & LESS CONDUCTIVITY , LESS SILICA Water . Another reason in MB IN TOP ANION RISEN IN BOTTAM CATION RISEN SO WHEN WATER COMS IN MB FIRST ITS ALKALI BECAUSE OF ANION RISEN AFTER ITS ACIDIC FOR CATION RISEN.

Answer / shaik.subhani

dm plant heart of the mb this meaning mixed bed first of all
sac out let water is coming now mbvessul top side anion
reesin bottom side cation resin water is comming anion that
is the high ph water converted to low ph

Answer / alok behera

In Mb, cation resin release H+ ion, and Anion resin released OH ion. That means H+ and OH- ion. So that is pure water. Normally pure water ph is 6.2 to 7.5. So mixed bed ph decrese.

Answer / amit katiyar

Mixed bed is used only for polishing of impurities which is remain or slippagefrom SBA like sio2 sodium act due to it lower size and shape. mixed bed contains both resin cation and anion so here remained inpurities are exchanged and pure water gained that means lower in ph conductivity and silica act.

Answer / adas

A 1.5 weight % aqueous salt solution is concentrated to 4 weight % in a single-effect evaporator. The feed rate to the evaporator is F = 7500 kg / h and the feed is at 85 degree Celsius. The evaporator operates at 1 bar. By assuming that only pure solvent of water exists in the form of vapor from the feed, calculate the flow rate of such vapor V.

Question 60 – During the landing process of an airplane, the velocity is constant at v. (a) If the displacement of the plane is x at time t, find the differential equation that relates t, x and v. (b) The plane has 2 parts of wheels – the front and the back, separated by a distance L. The front part of the wheel touches the land first, that allows the straight body of the plane to form an angle T with the horizontal land. If the vertical distance between the back part of the wheel and the horizontal land is y, find the equation of y as a function of L and T. (c) Find the differential equation that relates dy as a function of dt, v and sin T. (d) Find the differential equation that consist of dy as a function of y, L, v and dt. (e) Find the equation of y as a function of v, L, t and C where C is a constant. (f) When t = 0, prove that y = exp C as the initial value of y.
