TASK 1: SOLVE FOR THE VALUE OF PRESSURE
Problem Solving
Instructions; Analyze and solve the following problems. Enclose your final an-
swer in a box.
1. For the closed tank with Bourdon-tube gages tapped into it shown in figure 1, what is
the specific gravity of the oil and the pressure reading on gage C?
2.
A vertical conduit is carrying oil (S=0.95) as shown in figure 2. A differential mercury
manometer is tapped into the conduit at points A and B Determine the difference in
pressure between A and B when h=3in. What is the difference in piezometric head be-
tween A and B?
3. A device for measuring the specific weight of a liquid consists of a U-tube manometer.
The manometer tube has an internal diameter of 0.5 cm and originally has water in it.
Exactly 2cm^3 of unknown liquid is then poured into one leg of the manometer, and a
displacement of 5 cm is measured between the surfaces. What is the specific weight of
the unknown liquid?
4.
What is the maximum gage pressure in the odd tank shown in figure 5? Where will the
maximum pressure occur? What is the hydrostatic force acting on the top (CD) of the
last chamber on the right-hand side of the tank?
5. What is the pressure of the air inside the tank as shown in figure 6. Elevations are in m.
