Ammonia must be removed from an air stream containing $12\%$ moles of the

solute, water at $25\backslash$deg C and a total pressure of $1$ atm are used for this. The speed of the Feed gas is $60$ kmol$/$h m$2$ and water is $70$ kmol$/$h m$2.$

You need to Remove $95\%$ of ammonia from feed. If the transfer coefficient of

total volumetric mass in gas phase is K'ya $=100$ kmol$/$h m$3,$ determine the HTU $(5$pts$.),$ NTU $(15$ pts$.),$ the height of the required gasket
