Water flows upward in a pipe oriented at 30 degrees. The mercury manometer readsh= 12 cm. Bothfluids are at 20◦C. What is the pressure lossp1−p2in the pipe (in Pascals)?

The pressure difference in the pipe is 2666 Pa.

Explanation:

Given that,

Height = 12 cm

Angle = 30°

We need to calculate the height

Using formula of height

We need to calculate the pressure difference in the pipe

Using formula of pressure

Where, = density of mercury

= density of water

Put the value into the formula

Hence, The pressure difference in the pipe is 2666 Pa.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

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 ! =)
