For a cold dilute feed to produce thick viscous liquor, backward feeding as compared to forward feeding results in
Which of the following statements are true/ false?
1. In the market economy, the prices are determined by the level of demand and supply in the market.
2. Mixed economy is an economic system in which both the private and public sector have equal roles to play.
3. Planned economy is also known as a centralised economy, controlled economy or command economy.
4. In the market economy, governments do not have much role to play.
Statement 1: Forward feeding requires pumps for the feed at every step. Statement 2: In a backward feeding arrangement, the most concentrated feed is exposed to the maximum steam in order to remove heat. This is its advantage.
For the reaction, A = X + Y, the respective concentrations are CA, CX and CY. The forward reaction rate constant is kf and the backward reaction rate constant is kb. Choose the correct statement from the following:
P. At equilibrium, kf CA > kB CxCy
Q. If the reaction is irreversible than, kb CXCY = 0
R. The backward reaction rate will essentially be first order, if the forward reaction rate is first order.
S. Activation energy for the first order forward reaction will be independent of temperature.
Fqra cold viscous feed, backward feed gives __________ than forward feed.
Are these statements about the feeding mechanism of evaporatortrue? Statement 1: In forward feed, the most concentrated liquids will occur in the last effect. Statement 2: In forward feed, the liquid is pumped from one effect to the next against the pressure drops.
A backward feed multiple effect evaporator is better than forward feed for concentrating cold feed, because it provides
The output of the following Python code is similar to the alphabet . . . . . . . .
import turtlet=turtle.Pen()t1=turtle.Pen()t2=turtle.Pen()t.forward(100)t1.forward(100)t2.forward(100)t1.left(90)t1.forward(75)t2.right(90)t2.forward(75)
One disadvantage with backward feeding is that the feed gets very concentrated at the beginning few units itself and hence it’s difficult to feed it to the next evaporator unit.
The advantage of backward feed multiple effect evaporators over forward feed units is that
