In a textile manufacturing unit, wet cloth is dried in a stenter. The cloth entering the stenter has a moisture content of 52%, while the cloth leaving the stenter is 96% dry. If the production rate (output) from the stenter is 200 kg/hr, what is the quantity of steam required per hour? The steam entering the stenter has an enthalpy of 660 kcal/kg. The condensate leaving the stenter is at 170°C. Consider drying to take place at atmospheric pressure, where the latent heat of water is 540 kcal/kg.
