Acircuit consists of a power supply and two resistors r1 and r2 connected in parallel. an ammeter is placed to measure the current through the restive r1. the ammeter reads i1= 7.7ma and the values of the resistors are r1=6.0 k ohm and r2= 1.6 ohm. the power supply was turned off, then the circuit was modified. resistor r1 was replaced with a different resistor rnew= 1.2 ohm. the power supply is turned back on. it provides exactly the same voltage as originally. what is the new current through resistor rnew?

Air is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. air enters the heat exchanger at 95 kpa and 20°c at a rate of 0.6 m^3/s. the combustion gases (cp = 1.10 kj/kg°c) enter at 160°c at a rate of 0.95 kg/s and leave at 95°c. determine the rate of heat transfer to the air and its outlet temperature.
