100 gallons per minute flow of water at 50 degrees F passes through a theoretically 100% efficient heat exchanger. The hot side or energy to the heat exchanger is a 510 degree F hot gas (essentially steam).
Assuming the 510 degree hot gas will heat the water, what is the energy in BTU's needed to accomplish and what would the hot gas flow rate at 510 degrees need to be to perform this heating?
Hydrogen chloride gas, produced by burning chlorine with hydrogen, is required at a supply pressure of 600 kN/m2, gauge. The pressure can be achieved by either operating the burner under pressure or by compressing the hydrogen chloride gas.
1name the five classes of fire and give an example of each. describe how an extinguishing agent controls each class of
If a patient with thyroid disease consumes a sample of Na131I containing 10 of 131I, how long will it take for the amount of 131I to decrease to of the original amount?
U-235 undergoes many different fission reactions. For one such reaction, when U-235 is struck with a neutron, Ce-144 and Sr-90 are produced along with some neutrons and electrons.
question 1a identify the components of a fire triangleb explain the condition required for combustion process to be
The limestone is supplied with average dimension 1.5 cm and must be reduced to 20 mesh before feeding to the gasification process. Recommend equipment to achieve the desired particle size and estimate the work required.
The Cookenwythe Gas Company pumps propane gas to the nearby Noxious Chemicals, Inc., polypropylene production plant. The gas is metered at the noxious plant at 400m3/h at 4.7atm gauge and 30°C.
A gas stream is entering a separator at 1 mole/sec with mole fractions 15% A and 85% B. (Component 1 is A, component 2 is B.) At surface, the gas stream is 8 bar and 350K. Two streams exit the separator, one primarily of A (0.99 A1, 0.01 A2), and one..
Suppose that R2 is decreased to 0.5 min/ft2. Compare the old and new values of the ultimate gain and the critical frequency. Would you expect the control system performance to become better or worse, justify your answer.
A certain gas has a molecular weight of 30.0 a critical temperature of 310K. and a critical pressure of 4.5MPa. Calculate the density in kg/m3 of this gas at 465 K and 9.0MPa
the rate of flow to an ammonia synthesis reactor contains 25 mole ltbrgtnitrogen and the balance hydrogen. the flow
A standard practice in refineries is to use a holding tank in order to mix the light naphtha output of the refinery for quality control. During the first six hours of operation of the refinery, the stream feeding the holding tank at 200 kg/min had 30..
