An insulated piston-cylinder device contains 5 l of saturated liquid water at a constant pressure of 150 kpa. an electric resistance heater inside the cylinder is now turned on, and 1500 kj of energy is transferred to the steam. determine the entropy change of the water during this process. use steam tables. the entropy change of water during this process

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

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
