Question

The permeability of an aquifer (m/day) will ____________

(a) increase with an increase in temperature of water flowing through the aquifer

(b) decrease with an increase in temperature of water flowing through the aquifer

(c) not get affected by the change in temperature of water flowing through the aquifer

(d) increase up to 20°C and then decreases with the increase in the temperature of water flowing through the aquifer

This question was posed to me by my school teacher while I was bunking the class.

Query is from Aquifers and Their Type-2 topic in section Ground Water for Irrigation through Wells and Tubewells of Irrigation Engineering

Answer 1

The correct choice is (a) increase with an increase in temperature of water flowing through the aquifer

To elaborate: The permeability is inversely proportional to the viscosity of water and viscosity decreases with increase in temperature. Hence, permeability will increase with an increase in temperature.
