Apumpis used toraisethe pressure of a fluid, and it operatesby converting the mechanical shaft work to mechanicalenergyof the fluid flow. A gasoline pump is measured to consume 3.5kW ofmechanical shaftpower when operating. The diameters of the outlet and inlet of the pump are the same and the pressuredifferential between them is 7 kPa. Determine the maximum possible volumeflow rateof gas

maximum possible volume flow rate = V = 0.5m^3/s

Explanation:

Given power consumed = 3.5kW

pressure difference ( delta -P) = 7kPa

let maximum possible volume flow rate = V

The rate of flow of work = W = V x Delta -P

hence, V = W/delta P

V = 3.5/7

V = 0.5m^3/s

i think its 5049.

i hope this !

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.
