Propane (c3hs) is burned with air. analysis of the products of combustion shows that, the number of moles of : co2 is 8.6, co is 0.6, o2 is 7.2, h2o is 12.27, n2 is 83.6. determine the percent of theoretical air used in the combustion process

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
