1. You are asked to select a sensor that will follow the temperature in the piston of an internal combustion engine that will operate at 8000 RPM. The temperature will vary roughly sinusoidally during the cycle and the design requirement is that the sensor reach at least 90% of the peak temperatures. What must the time constant be

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
