A:A 60 Hz, 4 pole turbo-generator rated 10 MVA., 20 KV has stored energy in the rotor at
synchronous speed of 90 MJ.
(a) Find. M the anguler momentum.
(b)If the generator supply 10 MW load at synchronous speed, find rotor acceleration in
degrees/sec.² and in rpm/sec if the rotor drop to 5MW.
(c) If the rotor acceleration calculated in part (b) is maintained for 12 cycles, find the change in
torque angle and rotor speed in rpm at the end of this period.
5. Let's see why Heapsort is unstable. Consider the list [2,2',1]. Because the length is 3 we
know there is a call to converttomaxheap followed by two sets of swap, chop, and maxheapify.

Calculate the dry mass of activated sludge (✗a) produced in wastewater treatment
system where the flow rate is 7,500 m³/day, the BOD concentration in the primary
effluent (i.e., the BOD concentration in the wastewater going to the aeration basin)
is 75 mg/L, the soluble BOD concentration in the liquid effluent of the secondary
clarifier is 10 mg/L, and the system is operating with an SRT of 3 days. Assume true
yield is 0.5 g VSS per g BOD and the decay rate (i.e., bч or kd) is equal to 0.1 days
1. Assume the system does not achieve nitrification and that the mass of cell debris,
nonbiodegradable VSS, and influent inert TSS is negigible. Express your answer in
