Chapter 2, Problem 2.27P
Interpretation Introduction

Interpretation:

The magnitude and the location of the force acting on the inclined surface in the given figure are to be determined..

Concept Introduction:

The force (F)

acting on a surface due to a fluid above it is defined as:

  F=ρgzA ......... (1)

Here, ρ is the density of the fluid with height z , A is the area of the surface, and g is the acceleration due to gravity.

The Pythagoras theorem to be used to a right angled triangle is:

  H2=l2+b2 ......... (2)

Here, H is the hypotenuse, l is the length, and b is the base of the triangle.

9.4. A PID temperature controller is at steady state with an output pressure of 9 psig. The set point and process temperature are initially the same. At time = 0, the set point is increased at the rate of 0.5°F/min. The motion of the set point is in the direction of lower temperatures. If the current settings are PART 3 LINEAR CLOSED-LOOP SYSTEMS Ke = 2 psig/°F Ti = 1.25 min TD = 0.4 min plot the output pressure versus time.
