How much will it cost to train the entire company to use a recycling program if the training includes paper handouts? (Remember, the training will take one hour and a team of three people will take three hours each to create the training program.) With the current budget, is it possible to train the company and buy recycling carts if recycling pickup in your city is free? Assume the best choice for recycle carts in your area was $80 per cart.
Air at 1600 K, 30 bar enters a turbine operating at steady state and expands adiabatically to the exit, where the pressure is 2.05 bar. The isentropic turbine efficiency is 90%. Assume ideal gas behavior for the air and ignore kinetic and potential energy effects. Determine the temperature at the exit, in K, and the work developed, in kJ per kg of air flowing.
4.20 Problem in this exercise refer to the following instructions sequence: a. ADD R1, R2, R3 LW R2, 0(R1) LW R1, 4(R1) OR R3, R1, R2. b. LW R1, 0(R1) AND R1, R1, R2 LW R2. 0(R1) LW R1, 0(R3). 4.20.1<4.7> Find all data dependences in this instruction sequences. 4.20.2<4.7> Find all hazards in this sequence for a 5-stage pipeline with and then without fowarding.
At steady state, a well-insulated compressor takes in air at 60F, 14.2 lbf/in.2 , with a volumetric flow rate of 1200 ft3 /min, and compresses it to 500F, 120 lbf/in.2 Kinetic and potential energy changes from inlet to exit can be neglected. Determine the compressor power, in hp, and the volumetric flow rate at the exit, in ft3 /min.
Please match the following hazard with the correct descriptionHigh charges of static electricityHas approximately the same density as air and can beformed from materials like gas and the decompositionof organic matterCombustible dust concentrationsUsually found in the process of loading, unloading andconveying combustible materialCarbon monoxideCan be found in tanks used by thechemical and petroleum industryPyrophoric substancesCan have sufficient energy to produce sparksand ignite a flammable atmosphere
A pulse-jet baghouse is desired for a finished cement plant. Calculate the number of bags required to filter 500 m3/min of air with a dust loading of 3.0 g/m3. Each bag is 3.0 m long with a 0.13 m diameter. If the average pressure drop is 1.0 kPa and the main fan is 60% efficient, calculate the fan power in kW. If the pulse air volumetric flow rate is 0.5% of the filter airflow rate and the pulse air pressure is 6.0 atm, calculate the power drawn by a 50% efficient compressor (in kW).
