Always use significant figure rules. remember that these rules apply to all numbers that are measurements. in working this problem, assume the value of "g" to be 9.8 m/s2 with two (2) significant digits unless otherwise stated. if an engine operates on an input temperature of 800k and an exhaust temperature of 600k, calculate the efficiency of the engine. efficiency = %
Answers: 1
is the exhaust temperature

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
