CIVE 519 – IRRIGATION WATER MANAGEMENT   1st MID-TERM EXAM   Note: The value of each question is 37.5 points. The exam is open book/notes. Write down assumptions. You can use a calculator or laptop (no internet access), but do not use a cell phone. Work alone. Time allowed for the exam is 1:15 (h:min).  Q1 (37.5 points). A given soil has a volumetric water content at field capacity of 28% and at wilting point of 18%. The crop root zone depth (maximum) is 0.5 m.    Answer the following questions showing your work, steps, and units:    If the farmer only allows half of the available water to be depleted between irrigations, how much water (net irrigation (not considering irrigation efficiency, losses)) would the farmer need to apply (in “mm” of water depth)?   

Leptin is a hormone produced by ________________ cells that is involved in energy balance and fat storage.

The consensus of the EAL is that indirect calorimetry, when available, should be used for determining energy needs of overweight or obese clients.

According to Egan, “The decrease in fluid pressure along the tube reflects a cumulative energy loss, as predicted by the second law of thermodynamics.  Available energy decreases because frictional forces (flow resistance) oppose fluid flow.”  Where are the two places that these frictional forces exist?  

The Bernoulli principle states that as the flow through a tube increases, the pressure in the fluid will                     along with its potential energy.
