An explosion rips through a chemical plant. A 1000-ft3 tank containing compressed air at 100 atm is suspected. Site damage indicates that the windows in a structure 100 yards away are shattered. Is the mechanical explosion of this compressed air tank consistent with the damage reported, or is the explosion the result of some other process ...

A 10.0 ft compressed-air tank is being filled. Before the filling begins, the tank is open to the atmosphere. The reading on a Bourdon gauge mounted on the tank increases linearly from an initial value of 0.0 to 100 psi after 15 seconds. The temperature is constant at 72°F, and atmospheric pressure is 1 atm.

The initial design of the gas producer was such that it could be converted readily to operate either as a downdraft or as an updraft reactor. Also, the air intake could either be by suction from the engine or by forced draft from a compressed air tank. There was only a single air inlet at the side of the producer when it was operated as a down-draft reactor, so that the combustion zone was concentrated in the vicinity of this single air inlet. 

The simple running costs for daily operation of a chemical laboratory also escalated. This is easily seen on the example of fluids. Prior to the 1950s, water and gas for Bunsen burners were the only ones routinely provided. After the 1960s, supplies that became standard included compressed air tanks of helium, argon, nitrogen liquid nitrogen special oils for thermostatic baths or vacuum pumps etc. 

A compressed-air tank is to be repressurized to 40 bar by being connected to a high-pressure line containing air at 50 bar and 20° C. The repressurization of the tank occurs so quickly that the process can be assumed to be adiabatic also, there is no heat transfer from the air to the tank. For this illustration, assume air to be an ideal gas with Cy = 21 J/(mol K). 

If a pressure gauge on a compressed air tank reads 120 psi, assuming standard atmospheric pressure at sea level, what is the absolute pressure of air in... 

The compressor is a device that increases the pressure of air and pumps the compressed air into a tank. The compressed air tank is called a reservoir. The compressed air is then routed to the desired location through transmission lines. Transmission lines are tubing through which the compressed air flows. Control valves regulate the flow of gases. The pneumatic system uses a cylinder with a movable piston to convert its fluid power into mechanical power in the form of linear motion. 

PC. Several components are needed to supply the compressed air cleanly and safely to the microfluidic systems, such as a compressed air tank or an air compressor, a pressure reducing valve, and air filters. The schematic of a pneumatic actuated multilayer microfluidic chip with its pneumatic supporting systems can be shown in Fig. 3. 

The energy required to power the instrumentation and commands can be supplied by a small battery. The actuation energy of the valves may be supplied by small compressed air tanks in the same manner as for the safety-relief valves of many BWRs.
