In an experiment on a 90 v-notch the flow is collected in a 0.9 m diameter vertical cylindrical tank. it is found that the depth of water in the tank increases by 0.685 m in 16.8 s when the head over the notch is 0.2 m. determine the coefficient of discharge of the notch.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

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
