## Question:How to remove equation labels? in Maple

Maple

Pl. help me remove the equation labels or hide the equation labels in my doc enclosed. What should i do to prevent equation labels from forming in my document. Please refer last two rows in the table below from the document.

Thanks for helping.Ramakrishnan V

Conversion from ppm to % vol is 1ppm = 0.0001 %

Conversion from % vol to ppm is

Avagadro's law between mass and volume is

where T is abs temperature and M is molecular weight;

M/(0.08205T)]*ppm*((A/F)*EA+1) /ρex; Emission is mg/kg fuel

If SFC is x g/kWhr; then Mass flow of exhaust is  (x/1000)*[M/(0.08205T)]*ppm*((A/F)*EA+1) /ρex; Emission is mg/kWhr

If the distance covered per liter is DCL km/liter, then (SFC/1000)*(DCL)/  is distance covered in km/kWhr

1 g/cc = 1 kg/lit; 1kg/m3 = 1 g/lit; Fuel density  is 0.77 kg/lit

Emission in mg/km = 0.77*Emission is mg/kg fuel/(km/liter fuel)

SFC is in g/kWhr

Measured emission is  E in ppm

Excess Air percentage is EA in per unit point

Molecular Weight of pollutant is M g/mol

Molecular weight of air =  =  g/mol

Why in the above row, col2 and col3 have no equn nos?

What should i do to remove the equn numbers 11, 12 and 13?

Temperature of exhaust is in T K

Density of exhaust is say  kg/m3

DCL is distance covered per kWh

Emission in g/kWhr is

Emission g/g of fuel = Emission in g/kWhr/SFC in g/kWhrper

Emission in mg/km = 0.77*Emission is mg/kg fuel*(km/liter fuel)
