The clear plastic bottles used for carbonated beverages (sometimes also called “soda,” “pop,” or “soda pop”) are made from poly(ethylene terephthalate) (PET). The “fizz” in pop results from dissolved carbon dioxide (CO2); because PET is permeable to CO2, pop stored in PET bottles will eventually go “flat” (i.e., lose its fizz). A 20-oz. bottle of pop has a CO2 pressure of about 485 kPa inside the bottle, and the CO2 pressure outside the bottle is 0.6 kPa. The Permeability Constant of the PET bottle is 0.23 x 10^-13 cm3@STP.cm/cm2.s.Pa. Note: assume that each bottle has a surface area of 500 cm2 and a wall thickness of 0.07 cm. If the bottle must lose 750 (cm3 STP) of CO2 before the pop tastes flat, what is the shelf life in days for a bottle of pop? Round your answer to 0 decimal places.
The clear plastic bottles used for carbonated beverages (sometimes also called “soda,” “pop,” or “soda pop”) are made from poly(ethylene terephthalate) (PET). The “fizz” in pop results from dissolved carbon dioxide (CO2); because PET is permeable to CO2, pop stored in PET bottles will eventually go “flat” (i.e., lose its fizz). A 20-oz. bottle of pop has a CO2 pressure of about 570 kPa inside the bottle, and the CO2 pressure outside the bottle is 7 kPa. Assuming conditions of steady-state, calculate the diffusion flux in cm3 at STP/cm2.s of CO2 through the wall of the bottle. The Permeability Constant of the PET bottle is 0.23 x 10^-13 cm3@STP.cm/cm2.s.Pa. Note: assume that each bottle has a surface area of 500 cm2 and a wall thickness of 0.07 cm.

At the moment when the smoke layerreaches the top of the opening, the gas temperature is found to be 300°C. Ignoring anyheat losses to the boundaries, calculate how long the fire has been burning.
Determine the enthalpy of steam at 127 degrees celsius, at 80% quality, and flowing at the rate of 80kg/h, if it is used to heat fluid soup. What is the volume in m3 of steam required per hour of operation?
Steam is used to heat a cylindrical open tank of water until it boils, after which a proportion of the water in the tank is vaporised. The tank has an internal diameter of 1 m and is initially filled with water to a depth of 2 m. At the start of the process, this water is at 19°C and has a density of 998 kg/m3 . It may be assumed that ambient atmospheric pressure is 1 bar and that any effects arising from hydrostatic head can be ignored, as can heat losses from the tank to the surrounding environment. The heating medium is saturated steam at 5 bar, which enters a heating coil at the base of the tank at 5 kg/min, loses heat to the water in the tank and condenses to form saturated liquid condensate at this pressure. Using the steam table supplied: a) Find the temperature (°C) and power rating (kW) of the heater coil. b) Find the boiling point of the water in the tank under these conditions, and the time required to bring the water to this temperature. c) Find the proportion of water…
Steam generators are a type of heat exchanges that are used inpower plants to generate steam at desired pressure andtemperature (Fig. Q1.b). In a steam generator, saturated liquidwater at 30°C enters a 60-mm diameter tube at the volume flowrate of 12 L/s. After exchanging heat with hot gas, the waterchanges to steam and leaves the generator at a pressure of 9 MPaand a temperature of 400°C. During this process, the diameter ofthe water/steam tube does not change. Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). (i) Calculate the steam mass flow rate and inlet velocity of the steam? (ii) What is the exit velocity of the steam? (iii) Calculate the rate of heat transfer (in MW) required tochange the phase of liquid water to steam.
During processing in a steel mill, a 375kg steel casting at 800 degrees is quenched by plunging it into a 500-gal oil bath, which is initially 75 degrees . After the casting cools and the oil bath warms , what is the final tempertature of the two? The weight per unit volume of the oil is 7.5 lb/gal.
The capillary pressure for a channel of round cross section can be expressed as a function of the surface tension, the contact angle and the channel radius (the numerical factor is 2). Assume a transition of two coaxial channels of constant round cross sections. The larger one has a diameter of 2 mm and a contact angle of 80 degree, the narrower one a contact angle of 125 degree with the liquid. Calculate the other radius required so a liquid segment having one of its two menisci within either segment experiences a counter pressure of 15 mbar.
