    Re: pressure/temperature

    its thermodynamics and no its not from my textbook. For part a) i couldn't find a formula or anything that helps me work out the initial temperature. I'm thinking that i have to use the property tables for saturated water, and at 800kPa the saturated temperature is 170.41.would that be correct?
