The reading of the pressure gauge fitted on a vessel is 25 bar. The atmospheric pressure is 1.03 bar and the value of 'g' is 9.81 m/s<sup>2</sup>. The absolute pressure in the vessel is

A student wants to find the absolute pressure of water at a point below the surface of water. He has a barometer and a manometer pressure gauge. The barometer reads 1.3152 bar where as the manometer pressure gauge reads 0.3152 bar. What is the absolute pressure? (Assume that pressure at one end of the manometer is atmospheric.)

A

1 bar

B

1.6304 bar

C

0.3152 bar

D

1.3152 bar

In the function vpa(‘981’,10), why do we put 981 within inverted commas?

A

We can choose to not put the value within a pair of single inverted comma

B

We do it so that we don’t get an approximated value

C

We do it to get the exact value as MATLAB computes exact values, of numerical expressions, when declared within a string

D

We do it to get a floating-point approximated value, approximated to 14 digits
