1.the amplitude and the period of y=2cos(-/pi/4x) and sketch the graph of this function. Make sure to indicate key points on your graph.

2.As the Venturi coeffecient increases with increasing Reynolds number of flow in the throat. The reason for this is

1 the friction loss in the throat decreases with in erasing renolds number

2 friction Los in throat increases with decreasing reynolds number

3 the friction Los in throat increases with increasing Reynolds number

3.The pressure difference between a pitot tube reading and a piezo meter reading taken at the same location Ina venturimeter is equivalent to

1. The stagnation pressure head

2. The dynamic pressure head

3. The total pressure head

4.the potential head

4.The relative roughness ofa pipe is 0.0005, if the blasius equation is applicable for Thecflow Reynolds number above 2700 rather then 3000<Re<10^5 what will be the new exponent of the blasius equation?

1. 0.223

2. 0.250

3. 1.786

4. 1.750
