A coal-fired power plant produces a net electrical output of 500 MW. The composition of the coal burned is C= 72 %, H= 6 %, S= 3.5 %, O= 6 %, N= 1 %, and ash= 12 % by weight. It's heating value (HV) is 30200 kJ/kg. The net thermal efficiency is 36%. The annual capacity factor is 70 %.a)How many metric tons/day of SO2 are emitted if 97% of the sulfur in coal is converted to SO2?b) How many metric tons/day of NOx are emitted if the NOx emission rate is 265.0 ng/J?
The forces F1, F2, and F3, all of which act on point A of the bracket, arespecified in three different ways. Determine the x and y scalar components of each of the three forces.
Describe the use of productivity models for estimating land productivity. Provide details about various attributes that can be used and how the model is developed . Examples can be used to demonstrate model workability.
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
The block is acted by its weight W=200 lb, a horizontal force Q=600 lb, and the pressure P exerted by the inclined plane. The resultant R of these forces is up and parallel to the inclined thereby sliding the block up it. Determine P and R.
Sketch and annotate the wedge described above.
To provide knowledge and practice AutoCAD software package for engineering activities.
Compute the maximum acceptable tensile service load T that may act on a single angle L6x4x3/4 that is welded along only one leg to a gusset plate; thus, there are no holes. The service load is three times the dead load. Solve for a0 A36 steel.
Due to an error, the length L shown was 1.795 m instead of 1.80 m, thus there is a gap of 0.5 cm, which makes it difficult to bolt the bar on the structure. The engineer suggests the bar is heated up by - Delta in order to close the gap.
The belt starts from rest at time t=0 and its speed increases at a constant rate of 150mm/s^2. Knowing that the coefficient of static friction between the pacakges..
determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement
If this two-step process is replaced by a single isothermal expansion of the air from 800 K and 4 bar to some final pressure P, what is the value of P that make the work of the two processes the same
What is the length of a 2 degree increment along a (A) meridian and (B) parallel at 45N and 115W. Assume the radius of Earth is 6370 km.
