The equilibrium moisture content (EMC) of a hygroscopic material surrounded at least partially by air is the moisture content at which the material is neither gaining nor losing moisture . The value of the EMC depends on the material and the relative humidity and temperature of the air with which it is in contact.
[15.87% of 599.97 + 40.08 × ?] ÷ 4.04 = 8.082.02
31.98% of 449.99 = ? - 194.97 + 59.98% of 124.99
(?)2 + 3.113 = 22.92 – 61.03
[(5/6 of 719.81) + 30% of 499.79] × (√99.89 + 25% of 399.69) = ?
(47.981% of 295) + (24.91% of 245) =?
{(1799.89 ÷ 8.18) ÷ 9.09 + 175.15} = 25.05% of ?
(8.013 – 25.04) = ? + 11.98% of 2399.98
(29.98% of 9840) + ? + (19.899% of 8490) = 7560
(462.23 × 127.84 ÷ 153.88) ÷ √(31.98 × 7.92) = ? ÷ 15.15
