Explain what happens to the following quantities when a Rankine cycle is modified to include a reheat
You must also show why/how you came to you answer!!
a) The turbine work
b) The heat out of the condenser
c) The heat supplied to the boiler
d) The pump work
e) The quality of the steam (moister content) at the exit of the second stage turbine.
Consider high pressure steam at 400 degrees C and v =0.01567 m^3/kg. Obtain estimates of the pressure using (a) the van der Waals equation (b) the redlich-kwong equation. The actual pressure is 150 bar.
A power plant situated 20 km directly upwind from a protected old-growth forest emits SO2 at a rate of 120 g s-1with an effective stack height of 100 m (uH= 2 m s-1). Environmentalists claim that the acidic deposition is damaging the valuable fore..
What annual investment is required at 8% per year compounded annually to accumulate to $100,000 at the end of 20 years?
At a certain temperature T1, a 6.288x10^1 mm rod of a copper alloy containing 3.1715x10^1 at% Ni has a resistivity of 2.788x10^1 x 10-8 O-m.
a cylinder has 500 cm3 of water. after a mass of 100 grams of sand is poured into the cylinder and all air bubbles are removoed by a vacuum pump, the water level rises to 537.5 cm3. Dteremine the specific gravity on the sand
At the end of year 1 the piece of equipment is worth $15,000 and at the end of year 2 $13,000, and at the end of the third and final year the salvage value is equal to $9,000.Applying the straight line depreciation, calculate the depreciation expe..
If the tensil testing machine can apply no more than 925 lbs. of force to the specimen, calculate the maximum rod diameter that should be used. (precision 0.000)?
Often this content is measured in grams per cubic meter (g/m3). Assume that a cumulus cloud occupies a volume of one cubic kilometer, and its liquid water content is 0.210 g/m3.
On the two lane carriageways, roadworks restrict the width of both traffic lanes, generating a bottleneck to the traffic flow. The maximum flow per lane on the unobstructed carriageway is 2100 vehicles per hour whilst on the section under repairing t..
A long line of burning agricultural waste emits 0.3 g/m/s of particulate matter on a clear fall afternoon with winds blowing 3 m/s perpendicular to the line. Estimate the ground-level particulate concentration 400 m downwind from the line.
For the beam and loading shown, write the equation of he shear and bending-moment curves and determine the magnitude and location of the maximum bending moment
During a regeneration process, some steam is extracted from the turbine and is used to heat the liquid water leaving the pump. This does not seem like a smart thing to do since the extracted steam could produce
