A fine-grained soil has a liquid limit (LL) of 90 %, and a plasticity index (PI) of 51 %. Considering the water content (w) as large as 28 %.
a. Calculate the liquidity index (LI) and indicate the consistency of the soil. Moreover, classify this soil according to both the Unified Soil Classification System and the AASHTO system.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
