A closed heavy steel chamber is filled with water at 10°C and at atmospheric
pressure. If the temperature of water and the chamber is raised to 40°C, what will be
new pressure of water? The coefficient of thermal expansion of the steel is
1.17 x 10-5 per C, assume the chamber is unaffected by the water pressure. Use
specific weight of pure water as a function of temperature and pressure for conditions
where g = 9.81 m/s².

A storage tank contains oil and water as indicated in the figure. At the
point where the two liquids exert the resultant force, on the ABC side of
the tank, it has a width of 1.25 m, a load cell has been placed, making the
point of application coincide with the resultant force. Consider the relative
densities of oil 0.9, and water 1. The compression load cell consists of
two active arm meters, mounted on a rectangular steel bar (12 mm x 12
m), with four isoelastic gauges, according to the pattern indicated in the
figure (2 longitudinal and 2 transverse) and connected in a Wheatstone
bridge to 12 V. Determine:
