A steam power plant receives 2000 kJ of heat per unit mass of steam flowing through the steam generator when the steam flow
rate is 100 kg/s. If the fuel supplied to the combustion chamber
of the steam generator has a higher heating value of 40,000
kJ/kg of fuel and the combustion efficiency is 85%, determine the
required fuel flow rate, in kg/s.

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 controllers anticipates the future from the slope of errors over time? a)-proportional b)-on/off c)-integral d)-derivative.
