You can use mechanical energy change of a fluid during incompressible flow per unit mass to calculate maximum (ideal or no losses) energy flow rate generated for a dam in picture below (composed of hydraulic turbine and mechanical to electric generator). Where energy rate is given by $\Delta E_{mech} = \dot{m} \Delta e_{mech} = \dot{m} \left( \frac{P_2 - P_1}{\rho} + \frac{V_2^2 - V_1^2}{2} + g(z_2 - z_1) \right)$ (kW). What assumptions can you make for the pressure and velocity of water flow at locations 1 and 4.?? P1=P2 only P1=P2 and V1=V2 V1=V2 only P1=P2, but V1 is not equal to V2

A bookstore is testing two shipping firms to determine which company should deliver its packages. The company wants to test if the average time for Shipping Firm 1 is slower than the average shipping time for Shipping Firm 2. Packages were shipped to 36 locations using each of the companies. The results are as follows: Shipping Firm 1: mean delivery time = 13 hours, $s = 2.6$ hours, $n = 36$ Shipping Firm 2: mean delivery time = 14 hours, $s = 3.1$ hours, $n = 36$ Difference (Shipping Firm 1 time - Shipping Firm 2 time): mean = -1 hours, $s = 2.9$ hours, $n = 36$ The correct t-value for this question is: $\circ -2.07$ $\circ -5.55$ $\circ 5.55$ $\circ 2.07$
