Answer / totti

main difference b/w horizontal and vertical heat exchanger
is "residence time" fluid which flow in horizontal heat
exchanger gets more residence time as compared to vertical
heat exchanger.

Answer / sandeep singh

construction wise both r same but functionally they differ.vertical is mainly used when less floor area availible.and vertical required higher pumping cost also good for handling heat sensible material as resident time is much lower in comparision to the horizontal one.

Answer / daya gamane

In vertical heat exchanger film-wise condensation occurs while in horizontal heat exchanger drop wise condensation occur

Answer / ossus

1.Thermosyphon type HE is vertical HE and Kettle type HE is horizontal HE.

2.in horizontal position, pressure drop is negligible and in vertical position,pressure drop is significant and high.

3. If viscosity of bottom product of distillation column is very high then vertical position preferred and if low then horizontal position preferred.

4 in vertical position high circulation of fluid of possible and low circulation in horizontal position.

Answer / vishwarup sane

1. As the tubes are smooth, the condensation occurs on the surface of tubes, which makes the film over the surface of tubes leads to increase in thickness, as the thickness increases it's acts as a insulation and lower the effective heat transfer coefficient.
2. In vertical heat exchangers as we go downward the thickness of the film increases resulting lowers the heat transfer coefficient.
3. In horizontal heat exchanger the formation of film on the surface of tubes is there but the not as that much of vertical heat exchanger, so the heat transfer coefficient is higher in horizontal type heat exchanger than vertical type heat exchanger.

Answer / yousef

the vertical is better than horizontal when using steam as service side

Answer / magesh

Both are the same. Only the way it is erected. Normally HXs are placed horizontally. But in case of space constraints they can be erected vertically. In such a case other changes like the head of pump pumping fluid to the vertical HX may change.

Answer / muthu

same

Answer / nagarajan

both are same only difference is the flow of the fluids us
ed in H.E

Answer / shravan kumar

if an exchanger is placed horizontally then it is called
horizontal heat echanger. Simillarly of vertical heat
exchanger.

ENGINEERING MATERIAL - EXAMPLE 12.2 : At 150 degree Celsius, a mixture of 40 wt % Sn and 60 wt % Pb present, forming phases of alpha and beta. Chemical composition of Sn at each phase : CO (overall) : 40 %, CA (alpha) : 11 %, CB (beta) : 99 %. (a) State 2 reasons for the existences of alpha and beta phases for the mixture of Sn - Pb at 150 degree Celsius. (b) By using Lever Rule, calculate the weight fraction of each phase for alpha, WA = Q / (P + Q) and beta, WB = P / (P + Q) where Q = CB - CO and P = CO - CA.

Chemical Engineering Energy Balance - Please match the term A - E as follow with the stated definition : A. Yield. B. Selectivity. C. Relative saturation. D. Molal saturation. E. Absolute saturation. i. Answer : ? (moles of desired product formed) / (moles that would have been formed if there were no side reactions and the limiting reactant has reacted completely). ii. Answer : ? (moles of desired product formed) / (moles of undesired product formed). iii. Answer : ? (relative humidity 40 % means partial pressure of water vapour equals 4 / 10 of the vapour pressure of water at the system temperature). iv. Answer : ? (moles of vapour) / (moles of vapour dry gas). v. Answer : ? (mass of vapour) / (mass of dry gas).

QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - EXAMPLE 31.6 : In N + 1 Rule in Quantum Chemistry, whenever a spin 1 / 2 nucleus is adjacent to N other nuclei, it is split into N + 1 distinct peaks. In 1 peak or singlet, there is only 1 magnitude. In 2 peaks or doublet, the ratio of magnitude of each peak is 1 : 1. In 3 peaks or triplet, the ratio of magnitude of each peak is 1 : 2 : 1. In 4 peaks or quartet, the ratio of magnitude of each peak is 1 : 3 : 3 : 1. In 5 peaks or quintet, the ratio of magnitude of each peak is 1 : 4 : 6 : 4 : 1. (a) By using binomial coefficients or Triangle of Pascal find the ratio of magnitude of each peak if 6 peaks exists. (b) How many adjacent nuclei are available in a spin 1 / 2 nucleus in such situation of 6 peaks?

NATURAL GAS ENGINEERING - QUESTION 26.3 : The United States of America Energy Information Administration reports the following emissions in million metric tons of carbon dioxide in the world for year 2012 : Natural gas : 6799, petroleum : 11695, coal : 13787. Coal-fired electric power generation emits around 2000 pounds of carbon dioxide for every megawatt hour generated, which is almost double the carbon dioxide released by a natural gas-fired electric plant per megawatt hour generated. If 1 metric ton = 1000 kg and 1 pound = 0.4536 kg, estimate the total energy generated by natural gas in the world for year 2012, in gigawatt hour.
