In an industrial process 10kg of water per hour is to be heated from 20∘Cto80∘C. To do this steam at 150∘C is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at 90∘C then ___ kg of steam is required per hour. (Given: Specific heat of steam =1 calorie per g ∘C, latent heat of vaporization =540calg−1)

1.	In an industrial process 10kg of water per hour is to be heated from 20∘Cto80∘C. To do this steam at 150∘C is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at 90∘C then ___ kg of steam is required per hour. (Given: Specific heat of steam =1 calorie per g ∘C, latent heat of vaporization =540calg−1)
Answer» In an industrial process $10 k g$ of water per hour is to be heated from $20^{\circ} C to 80^{\circ} C$ . To do this steam at $150^{\circ} C$ is passed from a boiler into a copper coil immersed in water. The steam condenses in the coil and is returned to the boiler as water at $90^{\circ} C$ then ___ $k g$ of steam is required per hour. (Given: Specific heat of steam $= 1$ calorie per g $^{\circ} C$ , latent heat of vaporization $= 540 c a l g^{- 1}$ )
