The prince company, inc has 100 employees. in 2009, the employees worked a total of 350,000 hours annual and reported 145 injuries/illnesses. what is the incident rate for 2009? from the problem above if only 79 injuries/illnesses resulted in lost workdays or restricted work activity, what will the lost workday incident rate be for 2009?

for the problems, if needed, the values of 910,000 for death, 27,000 for loss work day incidents, and 7,000 for no lost work day.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

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
