the figure shows a tank within a tank, each containing air. pressure gage a is located inside tank b and reads 1.4 bar. the u-tube manometer connected to tank b contains mercury. using data on the diagram, determine the absolute pressures inside tank a and tank b, each in bar. the atmospheric pressure surrounding tank b is 101 kpa. the acceleration of gravity is g=9.8 m/s.

A manometer containing two oils is used to assess the pressure of air in a storage tank.  Given the configuration of the oils in the picture, calculate the pressure in the tank.  The density of air is negligible to the density of the oils (?oil1 = 1000 ??/m3; ?oil2 = 400 ??/m3 ). The height of oil 1 is 1 ?, and the height of oil 2 is 0.8 ?.  The atmospheric pressure is 98 ???. The manometer is ipen to the atmosphere.

A 60-ft3 compressor tank container has a gauge pressure of 160 Ib/in.? and a temperature of 75 °F. After some time, the temperature decreases to 25 °F. Part 4: What is the absolute pressure of the system after the temperature decreases? Round to nearest whole number - ### (no unit PSI))

Question #2: Pressure acts on a wall below as shown. The pressure varies with z-position on the wall by P = (z/100)2, where P has units of lb/ft². The wall width is 100 ft, while the wall height is 100 ft. Determine the magnitude and position of the resultant pressure on the wall. Give position in terms of both z and y axis. h a b O Figure P 100 y lb/ft²
