Determine the installed cost, tube length, and number of tubes for the optimum exchanger that will meet the following operating conditions and specifications:
(a) Twenty thousand pounds of air per hour is cooled from 150 to 100°F inside the tubes of a shell-and-tube exchanger.
(b) Water is used as the cooling medium. The water enters the unit at 70°F and leaves at 100°F.
(c) All other conditions are the same as those specified in Example 5 of this chapter, except that Bi is not given. 8. Present a detailed derivation of Eq. (481 in this chapter, using, as a starting point, any of the other equations that are given.
A geometrically similar 200 pump having a similar efficiency curve is used to pump water through 112.5 m of 150 mm pipe, f = 0.025. The static lift is 10 m. Neglecting minor losses in the pipe calculate the flow, head and power required to drive t..
Calculate the ?S for the transfer of one mole of octane to water using the change in multiplicities assumed for the first shell of water molecules surrounding the molecules.
A system can be represented by the block diagram below: Derive (write the different steps explicitly. not just the solution!) the closed-loop transfer function relating the set point (Ysp) to the output Y
At one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to saprotrophy to gain food. Why is this no longer considered a solid theory?
The band gap of indium gallium arsenide varies based on the concentration of gallium in the material. A sample of indium gallium arsenide absorbs light with a wavelength less than 1.37 microns. What is the band gap of the indium gallium arsenide samp..
Find the components of the convective momentum flux pvv inside and outside the slot - Evaluate the xx-component of pvv.
What is the empirical formula of this compound and does this compound behave as an ideal gas
In a specific rectification process , operating on ethanol and water mixtures, the vapor and liquid streams entering and leaving the column are those given in the table ethanol water mole% moles liquid entering top 75.1 24.9 liquid leaving bottom ..
Use the truncated virial equation along with the second virial coefficient calculated above to estimate the volume of water at 200 °C, 14 bar. How does this value compare with the volume obtained from the steam tables? Discuss this comparison.
question 1a with the help of a labeled drawing discriminate between the first-stage biochemical oxygen demand bod and
Develop a pro forma income statement for this strategy project in its 1st year of operation (Only to the level of EBIT)First identify the major cost drivers for this recommended entry strategy
A 1 m^3 isolated chamber with rigid walls is divided into two compartments of equal volume. The partition permits transfer of heat. One side contains a nonideal gas at 5 MPa and 300 K and the other side contains a perfect vacuum.
