¢¹ mass of water : Wm (g)
¢¹ temperature of water : Wt (¡É)
¢¹ specific heat of water : Ws (cal/g¡¤¡É)
¢¹ heat of vaporization of water : Wg (cal/g)
¢¹ specific heat of steam : Ss (cal/g¡¤¡É)
¢¹ temperature of steam : St (¡É)

1) Heat required to make water of Wt (¡É) to water of 100 (¡É)
¢¹ q1 = Wm*Ws*(100-Wt)

2) Heat required to make water of 100 (¡É) to steam of 100 (¡É)
¢¹ q2 = Wm*Wg

3) Heat required to make steam of 100 (¡É) to steam of St (¡É)
¢¹ q3 = Wm*Ss*(St-100)

4) Total heat required
¢¹ Q = q1+q2+q3 = Wm*(Ws*(100-Wt)+Wg+Ss*(St-100))

*** Âü°í¹®Çå[References] ***

Q = Wm*(Ws*(100-Wt)+Wg+Ss*(St-100))
