Consider the following statements: In case of helical gears, teeth are cut at an angle to the axis of rotation of the gears. 1) Helix angle introduces another ratio called axial contact ratio. 2) Transverse contact ratio is equal to axial contact ratio in helical gears. 3) Large transverse contact ratio does not allow multiple teeth to share the load. 4) Large axial contact ratio will cause larger axial force component Which of the above statements are correct?
What will be the extraction factor of the process of extraction for the first stage of the extraction under the staged counter current process of extraction?
Statement 1: Multi-stage cross-current extraction – the solids contain some amount of solute after every extraction. Statement 2: Single-stage batch extractor – Used in labs and not on large scale as a solvent is continuously subjected to heat.
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?

Power developed increases as local temperature decreases 3. Power developed is not dependent on local temperature. 4. Power developed increases as local atmospheric pressure increases. 5. Power developed increases as local atmospheric pressure decreases.
If the F1 generation produced by a cross between axial and terminal flower-bearing plants produces only axial flowers, the F2 progeny produced by the self-crossing of F1 will also produce only axial flowers.
Every stage of extractor act as mixer and settler in the extraction process.
Which of the following statement(s) are true with respect to the concept of ‘EFFICIENCY’ as used in mainstream economics? 1. Efficiency occurs when no possible organization of production can make anyone better off without making someone else worse off. 2. An economy is clearly inefficient if it is inside the Production Possibility Frontier (PPF). 3. At a minimum, an efficient economy is on its Production Possibility Frontier (PPF). 4. The terms such as ‘Pareto Efficiency’, ‘Pareto Optimality’ and ‘Allocative Efficiency’ are all essentially one and the same which denote ‘efficiency in resource allocation’. Select the correct answer using the code given below:
Pavan and Sravan are two persons. If Pavan works with his actual efficiency and Sravan twice of his actual efficiency then it takes 25 days to complete the work. But If Pavan works twice of his actual efficiency and Sravan with his normal efficiency then the work is completed in 20 days. How many days would it take if Sravan alone works with his actual efficiency (in Days)?
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 ?
