A stainless steel chamber contains Ar gas at a temperature T and pressure P. The total number of Ar atoms in the chamber is n. Now Ar gas in the chamber is replaced by CO2 gas and the total number of CO2 molecules in the chamber is n/2 at the same temperature T. The pressure in the chamber now is P’. Which one of the following relations holds true? (Both the gases behave as ideal gases)
Product X is produced by mixing chemical A and chemical B in the ratio of 5 : 4. Chemical A is prepared by mixing two raw materials, P and Q, in the ratio of 1 : 3. Chemical B is prepared by mixing raw materials, Q and R, in the ratio of 2 : 1. Then the final mixture is prepared by mixing 8640 units of product X with water. If the concentration of the raw material Q in the final mixture is 50%, how much water had been added to product X?
In machining system of AWJM, mixing chamber is immediately followed by which of the following component?
A mixed juice was prepared by mixing orange, apple and pineapple juices in the ratio 18 ∶ 16 ∶ 3 respectively. On adding 8 litres of orange juice and 4 litres of pineapple juice, the ratio of mixed juice changes to 5 ∶ 4 ∶ 1. How much apple juice should be further added to it, so that the ratio of mixed juice becomes 10 ∶ 9 ∶ 2?
A 60% spirit solution is mixed with r% spirit solution in the ratio 1 : 3 such that a s% spirit solution is obtained. When a (s/3)% spirit solution is mixed with 55% spirit solution in equal ratio, an (r/2)% spirit solution is obtained. Which of the following can be determined? (A) Value of ‘r’ (B) Value of ‘s’ (C) Volume of the 60% spirit solution mixed initially (D) If 9 liters of r% spirit solution was mixed initially, what was the volume of the s% spirit solution thus obtained?
The mixing vat in a factory receives liquid ingredients through six separate value--- labeled R.S.T.U,Y and Z -- each of which has exactly two settings: open and closed.The mixing vat operator must ensure that each valve is set open or closed according to the following conditions: If T is open, both S and Z must be closed, R and Z cannot both be closed at the same time; If Y is closed, Z must also be closed;S and U cannot both be open at the same time. Which of the following, if given to the mixing vat operator as an instruction, would not determine the setting of any other valve ?
Consider the following statements in respect of ‘mixers’ 1. Mass batch mixing of ingredients is the most desirable method. 2. Charging all materials into a drum mixer is done ‘at once’. 3. The quantity of material fed into a mixer should be not more than the quantity that can be used in less than 30 minutes after completion of mixing. 4. Reversing mixers have less capacity than tilting mixers. 5. In large mixers, additional time of mixing is allowed. Which of the above statements are correct?
The number of chambers in an office is odd. Every chamber has fans and bulbs. The number of bulbs in each chamber is twice the number of fans in that chamber. The number of bulbs is the same in all the chambers. The total number of fans and bulbs in all the chambers is thirty. What is the total number of chambers in the office?
