ROUND UP TO 4 DECIMAL PLACES. Draw and label the P-V & T-S diagrams. An Ideal air standard dual-combustion cycle has a compression ratio of 15. At the start of the compression process, the air temperature and pressure are 30°C and 150kPa respectively. Heat addition takes place until the maximum cycle temperature reaches 1950°C and produces total heat of 1200 kJ/kg. Determine (a) Temperature, specific volume and Pressure at each state, (b) Net work output (kJ/kg), and (c) thermal efficiency....

ROUND UP TO 4 DECIMAL PLACES. Draw and label the P-V & T-S diagrams. A gas turbine power plant operates on simple Brayton cycle with air as the working fluid. The pressure ratio is 12. Temperature at the compressor inlet is 300 K, while at the turbine inlet the temperature is 1000 K. Determine (a) the efficiency and (b) the net work output per kg of air. (c) Mass flow rate (kg/s) to produce 70,000 kW.

Calculus dictates that (∂U/∂V) T,Ni = T(∂S/∂V)T,Ni – p = T(∂p/∂T)V,Ni – p (a) Calculate (∂U/∂V) T,N for an ideal gas [ for which p = nRT/V ] (b) Calculate (∂U/∂V) T,N for a van der Waals gas [ for which p = nRT/(V–nb) – a (n/V)2 ] (c) Give a physical explanation for the difference between the two. (Note: Since the mole number n is just the particle number N divided by Avogadro’s number, holding one constant is equivalent...

(Round all intermediate calculations to at least 4 decimal places.) A machine that is programmed to package 2.05 pounds of cereal in each cereal box is being tested for its accuracy. In a sample of 26 cereal boxes, the mean and standard deviation are calculated as 2.08 pounds and 0.14 pound, respectively. Use Table 2. a. Select the null and the alternative hypotheses to determine if the machine is working improperly, that is, it is either underfilling or overfilling the...

(Round all intermediate calculations to at least 4 decimal places.) It is advertised that the average braking distance for a small car traveling at 75 miles per hour equals 120 feet. A transportation researcher wants to determine if the statement made in the advertisement is false. She randomly test drives 36 small cars at 120 miles per hour and records the braking distance. The sample average braking distance is computed as 111 feet. Assume that the population standard deviation is...
