The mercury manometer of fig. P2.57 indicates a differential reading of 0.30 m when the pressure in pipe a is 30-mm hg vacuum. Determine the pressure in pipe b.

The pressure in pipe b is 33.4 kpa.

Explanation:

Given that,

Pressure in pipe a = 30 mm hg vacuum

Differential reading = 0.30 m

We need to calculate the pressure in pipe b

Using diagram

Where, P = pressure

W= specific weight

Put the value into the formula

Put the value of specific weight

Hence, The pressure in pipe b is 33.4 kpa.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

none, its a machine
