Question 4
In case of cooling towers, the ratio of the rates of heat and mass transfer is indicated by the ______________ number ?
Question 5
In an absorption column, the flooding velocity for random packing is ___________________ that for stacked/regular packing?
Question 6
Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysteresis. In such cases, the desorption equilibrium pressure is ______________ that obtained for adsorption?

With increase in temperature, the leaching rate increases due to__________________?
Question 9
Large scale drying of wheat is done in a ________________ dryer?
Question 10
