C

0.3152 bar

D

1.3152 bar

The question below, there is a statement followed by two conclusions numbered I and II. You have to assume everything in the statement to be true. Then consider the 2 conclusion together and decide which of them follows beyond a reasonable doubt from the information given in the statement. Statement: High pressure boilers are hazardous pieces of equipment, which are strictly regulated with special laws. Conclusions: I. If not regulated, high pressure boilers will be easily available in the market II. High pressure boilers are rare.

A

Only conclusion I follows

B

Only conclusion II follows

C

Both conclusion I and II follows

D

Neither conclusion I nor II follows

Consider the following statements for dynamic characteristics of a measurement system: 1. Fidelity is defined as the degree to which a measurement system indicates changes in the measured quantity without any dynamic error. 2. Dynamic error is the difference between the true value of the quantity changing with time and the value indicated by the measurement system if no static error is assumed. 3. Measuring lag is the retardation in the response of a measurement system to changes in the measured quantity. Which of the above statements are correct?

A

1 and 2 only

B

1 and 3 only

C

1, 2 and 3

D

2 and 3 only
