A-Air at a temperature of 134°C and atmospheric pressure flows with a velocity of 7 m/s over a smooth 5 m long and 1 m wide cast iron plate. Under steady-state conditions, the air-side

surface temperature of the plates is at 120°C. Under the described conditions, determine the

overall heat transfer rate through the plate.

B-If the flat plate in (A) is replaced with a cylinder with the same surface area (heat transfer

area) and the cylinder's length is the same as the width of the plate (1.0 m), what would be the

heat transfer rate for cross air flow over the outside surface of the cylinder?

C. If the flat plate in (A) is replaced with a sphere with the same surface area (heat transfer area),

what would be the heat transfer rate for cross air flow over the outside surface of the sphere?

D- Based on your results, discuss which surface configuration is more effective for heat

dissipation and why.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

answer: mole of the gas
