Determine the work done by the impeller per kg of water. (8) Explain the working of single acting reciprocating pump with a neat sketch. (5) A single acting reciprocating pump has piston diameter 12.5 cm, and stroke length 30 cm. The center of the pump is 4 m above the water level in the sump. The diameter and length of suction pipe are 7.5 cm and 7 m respectively. The separation occurs if the absolute pressure head in the cylinder during suction stroke falls below 2.5 m of water. Calculate the maximum speed at which the pump can run without separation. Take atmospheric pressure head as 10.3 m of water. (9) Make a note on closed loop servo system.

Max. Marks: 70
Question No. 1 is compulsory and to be written at one place Answer any FOUR from the remaining All questions carry equal marks Use of statistical tables is allowed 1. (a) Distinguish between quality loss and quality cost. (b) What is ‘off-line’ quality control? (c) How type-I error is controlled? (d) What is a run with respect to a control chart? (e) Give two examples for nominal the better type product specifications. (f) What is process capability ratio? (g) Mention the difference between ATI and ASN. 2. (a) Explain the concept of six sigma. (4) (b) An ⎯X chart with three sigma limits has parameters as follows: UCL = 104 CL = 100 LCL = 96 n=5

What is the probability that the control chart would exhibit lack of control by at least the third point plotted? (10) 3. (a) What is the basis for using 3-sigma limits in control charts? Do you justify the same for attribute control charts? (7) (b) A fraction nonconforming control chart is to be established with a centre line of 0.01 and two-sigma control limits.
