Q4: A small, low-emission, stationary bas-turbine engine operates at full load (3950 kW) at an equivalence ratio of 0.286 with an air flow rate of 15.9kg/s. The equivalent composition of the fuel (natural gas) is C11oHa 32. Determine the fuel mass flow rate? Answer : 0.27kys

Detetrmine the formula mass, in amu, of diesel, C12H23. а. 147.31 с. 167.31 b. 157.31 d. Answer is not among the choices

6. A four-stroke, 6-cylinder, 3.6 Itr SI engine, is designed to have a maximum speed of 6000 r.p.m. At this speed, the volumetric efficiency of the engine is 0.92, fuel density is 700 kg/m C 15. Calculate: (1) %3! 0.85, C 0.6, Apg = 0.07 bar, at sea level T, = 27°C, p. = 1.03 bar, and AE Throat diameter of the carburetor. (2) Fuel orifice area. (3) AF at altitude of 4000 m

Consider the extraction of energy from the tail gases from a nitric acid adsorption tower, such as that described in Chapter 4, Example 4.4. Gas composition, kmol/h: 0₂ N₂ NO NO₂ H₂O 371.5 10,014.7 21.9 Trace saturated at 250°C If the gases leave the tower at 6 atm, 25°C, and are expanded to, say, 1.5 atm, calculate the turbine exit gas temperatures without preheat, and if the gases are preheated to 400°C with the reactor off-gas. Also, estimate the power recovered from the preheated gases.
