A fuel oil is analyzed and found to contain 85.0 wt% carbon, 12.0% elemental hydrogen (H), 1.7% sulfur, and the remainder noncombustible matter. The oil is burned with 20.0% excess air, based on complete combustion of the carbon to CO2, the hydrogen to H2O, and the sulfur to SO2. The oil is burned completely, but 8% of the carbon forms CO. Calculate the molar composition of the stack gas.
Materials Properties, Consider the following three engineering materials: (i) low-carbon steel; (ii) alumina; (iii) glass-fiber reinforced polymer.
Four kilograms of steam in a pistonlcylinder device at 400 kPa and 448.15 K (175°C) undergoes a mechanically reversible, isothermal compression to a final pressure such that the steam is just saturated. Determine Q and W for the process.
The blood shows 48 counts per minute of radioactivity. Calculate the volume of blood in the rat. What assumptions must be made in performing this calculation?
The formation of ice during colder weather helps temper the seasonal transition to winter. This is mainly because
Because of failure in the insulation there is a loss of 60 kJ per kg of steam. What is the power produced by the turbine if all inlet and outlet conditions remain the same?
The above stream is flashed isothermally to a pressure such that the vapor contains 90% carbon dioxide. Determine the pressure and the concentration of CO2 in the liquid.
Neglecting stator resistance and rotational losses, and assuming constant rotor resistance, determine the slip at maximum torque and the slip at full load.
What is the resultant force of the entire system? What are the magnitude and direction of acceleration of the weights?
Determine the 50- Hz applied voltage and the slip at which the motor will develop a torque equal to its 60-Hz full-load value.
From among the following, choose one which is not an exothermic process. 1. Ammonia synthesis 2. Methanol synthesis
Suppose the rails in Figure 10.5a have a resistance r[Ω/m] each. The bar is perfectly conducting. Calculate the current in the resistor R at a time t if the bar starts at t = 0 at x = 0 (x = 0 is at the location of R) and moves at constant speed v..
A hot water heater measures 20" in diameter. What is the area of a metal base for the water heater, assuming a four-inch overhang for the base beyond the edge of the heater? (Round to the nearest tenth.)
