You are analyzing the following (not necessarily well designed) process: At the start of the process, there two fluid streams, one containing species ‘A’ at a concentration of 2mol/l (Stream 1) and one containing species ‘B’ at a concentration of 3mol/l (Stream 2). Each stream has a control valve near the start of the process. Stream 1 has a temperature of 90°C and Stream 2 has a temperature of 70°C. The two streams enter a motorized mixer. A single stream exits the mixer (Stream 3). Stream 3 then enters a stirred tank reactor where nA+mB⟶C. The exit stream (Stream 4) enters a fluid separator. Out of the separator are two streams, one containing species ‘A’ and ‘B’ (Stream 5) and the other containing species ‘C’ at concentration of 1.5mol/l (Stream 6). Stream 5 goes back into the mixer. Stream 6 goes through a pump and another control valve. This stream is then cooled in a shell and tube heat exchanger using a cooled water stream that is at a temperature of 15°C. The outlet flow, now…
Your first customer asked for an air piston-cylinder to use it in air compressors for generating high pressure. Your role in your company is to analyze, describe the operation of the system and their properties, explain and demonstrate the application of the first law of thermodynamics to this system, as well as, illustrate the importance of expressions for work done in the system through the application of the first law. Air Figure 1:Schematic for the air piston-gylinder. The required piston-cylinder device is frictionless and initially contains 3 kg of air at 150 kPa in 0.2 m?. The air is now heated by using a fire. Also, a mechanical shaft is rotating. Then the piston starts
Suppose that you have designed a portable compressed-air supply system, as shown in the figure below,for filling scuba tanks and for driving pneumatics tools in garages and factories.The system consists of an electric motor, an air compressor, an air tank, a regulator and a pressure-reliefsafety valve.The regulator contains a pressure sensor connected to a power switch. The motor is switched on whenthe tank pressure drops bellow a fixed value and off at a slightly higher pressure. The pressure-reliefvalve is set to open at a higher pressure than the regulator motor off-pressure.Explosion of the tank is clearly a dangerous hazard. Three events are assumed to possibly lead to a tankexplosion:1. an internal tank defect such as poor welding2. an external cause such as a plant vehicle colliding with the tank3. Excess pressure in the tank. The excess pressure can occur only if both the control unit and thepressure-relief valve fail:The pressure sensor might fail to shut oof the motor because…

The figure below shows a schematic of a dual-duct system For design purposes, suppose the zones shown are two of five zones, each having identical operating design conditions. The only exhaust is the main system exhaust. The zones are to held at 75 °F db / 50% RH when the total heat gain of each one is 200,000 BTUH and the sensible heat ratio is 0.6. Outside air (OA) is 95 °F db / 40% RH and the system is designed to operate with a mass flow rate of dry air that contains 25% OA & 75% RA (return air). The hot deck provides sensible heating only, and the air exits the heating coil at 105 °F db. The cold deck is designed such that air exits the cooling coil at 50 °F db / 90 % RH. Take the pressure to be one standard atmosphere. a. Accurately sketch and label the state points on an electronic psych chart (in particular make sure that the coil is represented as a collie on the TRANE pscyh chart software you can input a coil process) b.
