PLEASE DO NOT USE PSYCHROMETRIC CHART. THANK YOU In the diagram below inlet air is drawn over a pool of liquid water in a steady-state, steady-flow isobaric process. Evaporation on the pool resultsin saturated air at the exit. The pool of liquid water is assumed to be at the same temperature as the exitair. Discharge fans at the exit provide a volumetric flow rate of 800,000 ft3/min. Problem #2: Assume that the R134a chiller is turned off such that Qout = 0, but the evaporative coolersystem continues to operate. Determine:a) The exit temperature, T2 (°F)b) The mass flow rate dry air through the system (lbm/sec).c) The rate of liquid water resupply required for continuous operation (lbm/hour).

What is the required diameter in meters of a cylindrical tank which has a length of 3 meters used for oil storage that will supply the engine for 5 days having a fuel consumption of 60Kg/hour at 27 degrees API? Please Answer # 9. If you can answer # 10 it will be appreciated much and rated high. Thanks!

A receiver must supply air to a pneumatic system consuming 30 scfm for 15 min between 140 psi and 110 psi. What size is required if the compressor is running and delivering air at 9 scfm? Group of answer choices 146.1 ft3 140 ft3 159 ft3 154.4 ft3 None of these are correct

What is the pressures required for safe pipeline transport of CO2?

I need unique and correct answer. Don't try to copy from anywhere. Do not give answer in image formet and hand writing

1. If 1 gallon of oil = 1.4 therm, how many gallons have been wasted by heat loss in Feb? (1 therm = 100,000 BTU)_____________________________________________________________________________________2. If $1.30 per therm, how much did you waste from house heat loss in Feb?

Thanks.

Throttling Valve Which of the following statements about flow through an insulated throttling valve are accurate? Answer ACCURATE or INACCURATE after each statement below. Velocities can be assumed to be small. Any reference to an "increase" should be interpreted as asking whether the quantity is greater on the downstream side of the valve. The enthalpy increases. downstream enthalpies are equal. a. and the upstream and b. Pressure increases sharply. and temperature increases sharply. C. There is negligible heat transfer with the surroundings.

10 m3 of free air is compressed to 8 bar gauge, every minute. What will be the air volumetric flowrate at the compressor exit if air is assumed an ideal gas ? please choose correct option a.1.11 m3/min b.2πdt m3/sec c.1.27 litre/sec d.1.11 m3/hour e.2.2 litre/sec

Can you do it in 50 mints

The venturi of a simple carburettor has a throat diameter of 20 mm and the coefficient of flow is 0.8. The fuel orifice has a diameter of 1.14 mm and the coefficient of fuel flow is 0.65. The density of air and fuel to be 1.20 kg/m and 750 kg/m. When the nozzle tip is neglected the air fuel ratio for a pressure drop of 0.8 bar is 1) 15.15 3 2) 13.1 3) 12.5 4) 16.0

intake valve intake compression JO BI Tuel injector the temperature of the gas; power exnaust vaive 0010 exhaust The diagrams show the cylinder of a petrol engine in 4 stages. Petrol vapour and air are drawn into the cylinder, The mixture is then squeezed together, and then exploded by a spark. The explosion pushes down the piston. The exhaust gases are then expelled from the cylinder. Use the first law of thermodynamics to analyse the energy changes during the process. At each stage explain what happens to i) the pressure of the gas; ii)
