Water at a flow rate of 0.009 m3/s travels from the lower reservoir to the upper reservoir.  The piping system consists of 220 m cast iron pipe with an inner diameter of 6 cm.  The system contains a sharp inlet, two standard 90° elbows, an open gate valve, and sharp submerged exit into the upper reservoir.   Use the density of water as 998 kg/m3 and the viscosity as 1.0×10-3 kg/(m*s).  The Moody diagram is shown below and on the second page of the equation sheet. [15 points]  Determine the frictional head loss due to the total pipe length.  You can use the Moody diagram below or an equation to find the Darcy friction factor. [5 points] Determine the minor head loses in this system.  [13 points] Determine the power required to operate the pump if it is 85% efficient.  Enter only the number, not units in the blank below. Include three digits in your answer and give the numerical answer in kW.

The water is to be pumped from the lower reservoir to the upper reservoir at a flow rate of [w] kg/s.  The free surface of the upper reservoir is [x] meters above the free surface of the lower reservoir.  The piping system shown has a pipe diameter of [y] cm and a total frictional loss (major and minor) of [z] meters.  The pipe entrance is 4 meters below the free surface of the lower reservoir and the pipe exit is 2 meters below the free surface of the upper reservoir.  Determine the power required to pump the water if the pump is 85% efficient.  Use the water density as 998 kg/m3.    In the blank below, enter the pump power in kW.  Write your answer to three significant digits and do not include units.

If a functions SRY gene has been transferred to one of the X chromosomes in an XX individual, the Wolffian ducts will _____ and the Mullerian ducts will _____.

If the pitot static probe measures a mercury height of h2= [x] cm, what is the velocity of the approaching water flow in the pipe?  Use h1=4 cm, 998 kg/m2 for the density of water and 13550 kg/m2 for the density of mercury. Start your solution writing the full Bernoulli Equation from the equation sheet.  Then simplify the equation for this problem.  As a final step, substitute values from the manometer shown.  You will be given partial credit for showing each step described.  Use properties given above.  In the blank below, enter the velocity in m/s.  Write your answer to three significant digits and do not include units.
