Here, we want to become proficient at changing units so that we can perform calculations as needed. the basic heat transfer equation is q = m*cp*t, where q is the amount of heat added or subtracted, cp is the constant pressure heat capacity, and t is the change in temperature (t = t2 – t1). for example, we need to heat 100 lbs of water from 25 °c to 75 °c. how much energy must we add to the water if the constant pressure heat capacity of water is 4.18 j/g k? (give answer in both kj and btu)

Acompressor receives the shaft work to decrease the pressure of the fluid. 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

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
