Question: How to remove equation labels? in 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 % = 10000*ppm

Avagadro's law between mass and volume is

"22.4 nm^(3)=1 kg mol; 22.4 lit = 1 g mol; at  101.325 kPa*(normal pressure) and (273+C ) K;"

ppm = 0.8205e-1*T*mg/(M*nm^3); mg/nm^3 = M*ppm/(0.8205e-1*T)

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)/`ρ__f`  is distance covered in km/kWhrNULL

[kg*km/(kWh*liter)*(liter/kg) = km/kWh]

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

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

[(kg/liter*(mg/kg))*km/liter = mg/km]

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 = .21*32+.79*28 = 28.84 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 `ρ__ex` kg/m3 

DCL is distance covered per kWh

SFC := 100*g/kWh; ppm := 4.3; EA := .2; M := 28; `ρ__ex` := .457; T = 400

100*g/kWh

(14)

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)
