Use the Rankine cycle. The boiler operates at a 1000 kpa with a maximum temperature of 30 degrees Celsius. The condenser is isobaric and operates at -5 degrees Celsius.
a) calculate the vapor quality leaving the turbine and the specific enthalpy exiting the turbine (in kj/kg).
b) determine the specific-work produced by the rankine cycle turbine (kj/kg), assuming it is ideal and adiabatic.
c) show the cycle on a t-s diagram.
d) determine the specific work required by the rankine cycle pump (in kj/kg), assume it is ideal and adiabatic.
e) determine the specific QH for the rankine cycle (kj/kg).
F) calculate the rankine cycle (thermal) efficiency.
g) Compare the required material strength and cycle efficiency of this rankine cycle with a carnot cycle operating with the same TH (30 degrees celsius) and TL is (-5 degrees celsius) by calculating the percent change in max pressure and thermal efficiencies. assume steam
The following data are the temperatures (in °F) of effluent at discharge from a sewage treatment facility on consecutive days: 43 47 51 48 52 50 46 49 45 52 46 51 44 49 46 51 59 45 44 50 48 50 49 50
Discuss the dangers of optimization in terms of minimum section to support loads. In other words, how would optimizing for bending stresses affect the shear capacity of a section
The motion of a particle is defined as x=t^2-8t+7 and y=0.5t^2+2t+4, where x and y are in meters and t is in seconds. Determine the magnitude of the smallest velocity reached by the particle, and the time, position, and direction of that velocity.
Determine the maximum rimpull of the tractor in each of the indicated gears if the efficiency is 92%. If the tractor is operated over a haul road whose slope is +2.5% with rolling resistance of 80 lb/ton
A 3-mi section of a two-lane, two-way highway located in a mountainous terrain is to be designed to carry a peak hour volume of 750 vehicles. Using the operational level of analysis
Develop a table that shows: 1) How many gallons of water are contained in the tank if the volume is measured in increments of 1 ft from the bottom to the top. 2) The mass of water at each increment, expressed in lbm.
If the arm is pulled back such that s= 100 mm and released, determine the speed of the 0.41-kg pinball B just before the plunger strikes the stop, i.e., s= 0. Assume all surfaces of contact to be smooth.
The discharge of the river at the basin outlet is measured at an avarage of 650 cfs. assuming that the charge in storage for the system is essentially zero, estimate the ET losses for the area in inches and centimeters for the year
How accurately would each 100-ft distance have to be measured so that the 95% error would no exceeded +-0.24ft in a total distance of 4000ft
The bus B has a weight of 15,000 lb and is traveling to the right at 5ft/s. Meanwhile a 3,000 lb car A is traveling at 4ft/s to the left. If the vehicles crash head-on and become entagled, determine their common velocity just after the collision.
what is the definition of critical state. explain at which stage a critical state may be approached in a drained triaxial text on a overconsolidated clay using stress path and strain-strain plot.
A tow truck is searching a city street at 30 mi/h for illegally parked vehicles. It travels over an equal tangent vertical curve with an initial grade of +3.5% and final grade of -4.0%.
