Are these statements about the pressure drop in filtration true? Statement 1: Due to the increase in the solids deposit in the pores. Statement 2: For constant solids concentration at the inlet increase in this pressure drop with time is constant.

Are these statements about the pressure drop in filtration true? Statement 1: Due to the increase in the solids deposit in the pores. Statement 2: For constant solids concentration at the inlet increase in this pressure drop with time is constant. Correct Answer True, True

The filter media exhibit a resistance to flow, which is increased by the solids deposit in the pores. For constant solids concentration at the inlet and constant retention the increase in this pressure drop with time is constant.

Mohan deposit certain amount in bank saving account for 6 year which give simple interest of x% annually and invest same principle in fix deposit for 2 year which gives interest rate 10% and compounded annually, total interest he get from saving account to fix deposit in the ratio of 6 : 7, if bank provide (x + 3)% rate annually on saving account deposit, then difference of interest arise Rs.7,500 between saving account and fix deposit after respective time period, what amount he invest in fix deposit?
In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
Consider the following statements regarding removal of impurities from water: 1. Settleable solids are removed by filtration. 2. Volatile solids are removed through sedimentation. 3. Dissolved solids are removed through reverse osmosis. 4. Colloidal solids are removed by coagulation. Which of the above statements are correct?
The rate of infiltration normally declines rapidly during the early part of rainstorm event and reaches a constant value after several hours of rainfall. The factors responsible for this phenomenon are I. the filling of fine soil pores with water, which reduces capillary forces II. moistened soil, clay particles to swell and reduce the size of pores III. raindrop impact breaking up with soil clumps, splashing fine particles into pores

In the following question, two statements are numbered as A and B. On solving these statements, we get quantities A and B respectively. Solve both quantities and choose the correct option. Quantity A: There are two inlet pipes A, B and two outlet pipes C, D inlet pipe B takes 7 hours more to fill the tank when compared to A. Two outlet pipes when working together can empty the tank in 3.5 hours and efficiency of both the pipe is same if all of them working together can fill the tank in 2 hours. Calculate the time taken by A to fill the tank. Quantity B: The ratio of efficiencies of two pipes A and B is in the ratio 3 ∶ 2 and that of pipe B and C is 1 ∶ 3. Pipe A and B are inlet pipes, pipe C is outlet pipe working together they can fill the tank in 7.5 hours. Calculate the time taken by A to fill the tank when working alone.
The following questions have three statements. Study the question and the statements and decide which of the statement(s) is/are necessary to answer the question. In how many hours tap B can fill the completely empty tank? Statement I: The inlet tap A and the outlet tap C working simultaneously takes 40 hours to fill the tank. Statement II: Efficiency of inlet tap B is equal to efficiency of outlet tap C or 62.5% of the efficiency of inlet tap A. Statement III: The outlet tap C can empty a half filled tank in 12 hours.
An Inlet pipe fills the tank at the rate of 3.5 liters/hour. And due to leak tank gets empty in 20% of time taken by both inlet and leak together. When the tank is full and due to leak and inlet pipe, the tank gets emptied in 60 hours. Find the capacity of the tank?
The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings. A steady state will eventually be reached when the concentration everywhere reaches a constant value. Provided D is independent of concentration there will be a single concentration gradient in the wall and the thickness of the wall is L, the flux is given by________________
