If a brass wire is 4 cm long with a diameter of 1.3 cm, can you use the set-up in this lab to measure its resistance? (Hint: consider the limitation of sensitivity for measuring voltage.) ( No. The voltage over the wire is 0.022 mV at 1.0 A and only 0.044 mV even at 2.0 A!)

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
