Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at 300 k, 2 bar, and a volume of 4 m3, is stirred until its temperature is 600 k. assuming the ideal gas model for the air, and ignoring kinetic and potential energy, determine :

(a) the final pressure, in bar.
(b) the work, in kj.
(c) the amount of entropy produced, in kj/k.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Which of the following controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
