Estimate the design-stage uncertainty in determining the voltage drop(v)across an electric heatingelement. the device has a nominal resistance of 30 ωand power rating of 500 w. available is anohmmeter (accuracy: within 0.5%; resolution: 1 v) and ammeter (accuracy: within 0.1%; resolution: 100 ma).

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Have a greater impact on maintenance productivity than any other support group. (clo5) a)-the top management b)-inventory and purchasing c)-sub-contracting d)-cmms

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
