# percentage mass

## percentage mass

calculation to convert drug concentration in solution (%) to mass (in mg); based on the principle that 1% solution contains 10mg of drug per 1mL of solution (see Table 1)
 Solution strength expressed as a percentage Solution strength expressed as percentage mass (mg/mL)(A ) Example of volume administered (B ) Total mass of drug administered (A × B ) 0.25% 2.5mg 10mL 25mg 2.5mg 20mL 50mg 0.5% 5mg 15mL 75mg 5mg 20mL 100mg 1% 10mg 5mL 50mg 10mg 10mL 100mg 2% 20mg 4mL 80mg 20mg 10mL 200mg Note: 1% solution contains 10mg of solute per millilitre of solution.The percentage mass is used in the calculation of the maximum safe dose (MSD) of an administered drug (where MSD is the maximum dose that can be administered in 24 hours, in relation to the body mass of the patient, the volume of drug injected and the strength [%] of the drug in solution; the MSDs of individual anaesthetic drugs vary - see Table 2).
 Agent (brand name) Maximum safe dose (70-kg adult) Dose per kg of body mass Lidocaine (Xylocaine) 200mg 3mg/kg Bupivacaine (Marcain) 150mg 2mg/kg Levo-bupivacaine (Chirocaine) 150mg 2mg/kg Mepivacaine (Scandonest) 400mg 6mg/kg Prilocaine (Citanest) 400mg 6mg/kg Ropivacaine (Naropin) 250mg 3.5mg/kg

where [psi] is the percentage mass loss of the reinforcement.
However, a simplified methodology is used in this research to modify the confined concrete material model (which is a function of the percentage mass loss in horizontal tie reinforcement) to account for the effect of corrosion damage.
Therefore, the previously defined equations for reinforcing steel can be used to modify the cross-sectional area, yield strength, and fracture strain of tie reinforcement as a function of the percentage mass loss.
Reference [49] employed this method in nonlinear finite element analysis of corrosion damaged RC beams with modified constitutive model for the cracked cover concrete as a function of percentage mass loss and validated this against experimental results.
LPG terminology used in the following equations represents LPG in percentage mass out of the total diesel fuel mass equivalent.
If the quantity of any single or several adjacent narrow fractions in repair materials is high, the section of RAP gradation broken-line appears to be steeper (the difference between the percentage mass passing the adjacent sieves increases).
