The vacuum pressure of a condenser is given to be 63 kPa. If the atmospheric pressure is 98 kPa, what is the gage pressure and absolute pressure in kPa, kN/m2, psi, and mmHg.   The absolute pressure is ____  kPa,___  kN/m2,_____  lbf/in2, _____ psi, or ______ mmHg.

1. Consider the following schematic of a power plant (operating in what is called a 'Rankine Cycle') Turbine Steam generator Condenser Coling water Economiaer The power plant control room reports that the plant is operating continuously at the following peak load conditions: a. Power to pump = 300KW b. Rate of steam flow = 25 kg/s c. Cooling water temperature at condenser inlet = 13 C d. Cooling water temperature at condenser outlet = 34 C Additionally, the following measurements were made at various points in the piping connecting the power plant components Data Pressure Temp.

What is the effect of temperature on Kw

HW9 In an engine governor of the Porter type, the upper and lower arms are 300 mm and 350 mm respectively and pivoted on the axis of rotation. The mass of the central load is 17 kg, the mass of each ball is 3 kg and friction of the sleeve together with the resistance of the operating gear is equal to a load of 27 N at the sleeve. If the limiting inclinations of the upper arms to the vertical are 35° and 45°, find, taking friction into account, the range of speed of the governor and Sensitiveness of Governors.
