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.
Calculate the dry unit weight, the saturated unit weight and the buoyant unit weight of a soil having a void ratio of 0.70 and a value of Gs of 2.72. Calculate also the unit weight and water content at a degree of saturation of 75%.
1. why the prediction are less than the observed result of connection in tension experiment?2. what difference does the
A man bought a 5% tax-free municipal bond .It cost $1000 and will pay $50 interest each year for 20 years.At maturity the bond returns the original $1000 .If there is 2% annual inflation
Discussion on how sustainability and green engineering can be integrated in the four components of materials science and engineering?
The tower crane is used to hoist the 2-Mg load upward at constant velocity. The 1.5-Mg jib BD , 0.5-Mg jib BC , and 6-Mg counterweight C have centers of mass at G1 , G2 , and G3 , respectively.
The relative roughness ofa pipe is 0.0005, if the blasius equation is applicable for Thecflow Reynolds number above 2700 rather then 3000
In the summer, the density at the top of the lake is 997 kg/m3, and at the bottom is 1000 kg/m3. Would you predict stratification to be present, and if so assume an epilimnion depth of 4m. Will the pesticides threaten the fish population during the s..
A field sample of medium sand with median grain size of 0.84 mm will be tested to determine the hydraulic conductivity using a constant-head permeameter. The sample has the length of 30 cm and a diameter of 5 cm.
assuming the entire system has reached equilibrium what is the distance that must be used between the inputs shown and
water from a waste water treatment plant is released into a receiving pond that has a volume of 5 ac-ft. one of the reasons for doing this is to assure that the chlorine residual is below 0.1mg/L before the water is released to a stream as require..
Two large water reservoirs are connected by 8,000 ft of schedule 40 steel pipe. The level of one reservoir is 500 ft above the level of the other
If the initial concentration of parathion in the runoff from the agricultural field is 3 ppb, the velocity of the river is 2.3 miles/day, how many days will the fish hatchery have to contain river water in holding tanks until the parathion concent..
