The image above represents a horizontal pipe with a constant crosssectional area of $9$ square inches; the pipe is filled with fluid which is flowing to the right. $\backslash ($ A B $\backslash )$ represents a section of that pipe. The absolute pressure at $\backslash ($ B $\backslash )$ is $29$ psi.

Determine in pounds the force at B of downstream pressure on the fluid in section $\backslash ($ A B $\backslash ).$ Your answer should include at least one digit after the decimal place.

Answer with a positive number if the force is to the right and a negative number if the force is to the left.
