You are to spray an 80-acre field that will be planted to alfalfa with 32 oz/ac Roundup, 1.5 pints/ac of Treflan, and 17lbs AMS/100 gallon spray. If your sprayer is calibrated to apply 10GPA carrier volume and holds 800-gallons how much AMS do you need to add to your sprayer to condition your water, and how many gallons of Roundup and Treflan do you need to add to your sprayer so that you apply the proper rate?
-Gas supply line- Gas A 1.5 m3 tank initially contains a gas at 140 kPa, 340 K. The tank is connected a line carrying same gas at 1400 kPa and 340 K. What should be heat transfer during this process, in kJ, so that the final pressure and temperature are 1400 kPa and 340 K, respectively. (cp=0.72 kJ/kg.K, cv=0.48 kJ/kg.K).
I need to solve question 2.
Atmospheric air is conditioned using an air conditioning before is supplied to a room. The following conditions were measured for dry air flow rate of 1 kg/s: Room air (outlet condition): • Relative Humidity (RH): 55.0 % • Dew point temperature: 10.7 °C Supply air (inlet condition): • Dry-bulb Temperature: 31.0 °C • Wet-Bulb Temperature: 22.6 °C 1. State all assumptions and include reference(s). 2. Estimate the inlet conditions (Relative humidity, dew point temperature, enthalpy, specific volume) based on the psychrometric chart 3. Estimate the outlet conditions (Dry-bulb Temperature, wet-bulb temperature, humidity ratio, specific volume) based on the psychrometric chart. 4. How much water in g/s was removed/added? Note: you must indicate if water was removed or added. 5. How much total heat or energy in kW was removed/added? Note: you must indicate if heat was removed or added. 6. What is sensible heat in kW for these conditions?
Gas supply line- Gas A 2.1 m3 tank initially contains a gas at 170 kPa, 370 K. The tank is connected a line carrying same gas at 1700 kPa and 370 K. What should be heat transfer during this process, in kJ, so that the final pressure and temperature are 1700 kPa and 370 K, respectively. (cp=D0.92 kJ/kg.K, c=0.64 kJ/kg.K).
Please explain why you used that formula to avoid confusion.
An air-cooled condenser has an expected U value of 30 based on the air-side area. The m²-k condenser is to transfer 60 kW with an airflow rate of 15 kg/s entering at 35°C. If the condensing temperature is to be 48°C, what is the required air-side area? Recall Cp,air = 1.0- kg-K kJ
