A piston-cylinder assembly contains 1kg of water, initially occupying a volume of 0.5m^3 at 1bar. Energy transfer by heat to the water results in an expansion at constant temperature to a final volume of 1.694m^3. Kinetic and potential energy effects are negligible. For water (a). Show the process on a T-v diagram. (b) evaluate the work in kJ and (c) evaluate the heat transfer in kJ.
In order to increase production rate, a reactor setpoint was increased from 160 psig to 190 psig. The reactor pressure transmitter was recalibrated from 0- 200 psig to 0- 300 psig. What is the percent span for the old and new setpoints?
