In a heat engine, water vapor flows into a turbine and then it enters a condenser for rejecting thermal energy. The system requires maintaining the gauge pressure of the steam at 1400 kPa at the turbine inlet and at a vacuum of 71 cmHg in the condenser. Having that the barometric pressure is measured as 77.2 cmHg, calculate the absolute pressures (in kPa) of the steam at the turbine inlet and in the condenser. (Density of mercury is 13600 kg/m3)

When measuring small pressure differences with a manometer, one arm of the manometer may be inclined to improve the accuracy of the reading. (The pressure difference is still proportional to the vertical distance and not the actual length of ghr fluid along the tube.) The air pressure in a circular duct is to be measured using a manometer whose open arm is inclined 25 degrees from horizontal. The density of the fluid in the manometer is 900 kg/m³, and the vertical distance between the fluid levels in the two arms of the manometer is 7.8 inches. Determine the gauge pressure of the air in the duct and the length of the fluid column in the inclined arm above the fluid level in the vertical arm.
