Wheatstone bridge. Suppose R3-100 2(2, R4 200 2 Ω, R2 is variable calibrated resistor, and R 100. ... Suppose R3-100 2(2, R4 200 2 Ω, R2 Is Variable Calibrated Resistor, And R 100 ± 1 Ω Is The Transducer Resistance. Calculate The Means And Uncertainty Of R2, That Is Required To Balance The Bridge?

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

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

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?
