Question 1 6 points penstock turbine Water in a reservoir at 20°C has a surface 28.9 m above the penstock (feed pipe) for a small hydroturbine. Ambient pressure above the reservoir is 100 kPa (absolute). Water enters a 150 m-long horizontal penstock at a flow rate of 0.145 m³/s. The turbine is 85% efficient. The pressure and velocity at the turbine exit are 90.0 kPa (absolute) and 4.5 m/s (so the exiting kinetic energy is not negligible). The mechanical energy loss (in the penstock), $gh_L$, is $0.015 \frac{L}{D} \frac{V^2}{2}$ (so the velocity is the penstock velocity). If the desired turbine output power is 27.0 kW, what is the minimum penstock pipe diameter? (Report all answers to 3 significant digits and note the units.) 29.0 cm Section Attempt 2 of 3 Verify

If to a good approximation the temperature dependence of critical field $B_c$ is $B_c(T) = B_c(0) \left[1 - \left(\frac{T}{T_c}\right)^2\right]$ Deduce that the approximate temperature dependence for the different is heat capacity per unit volume becomes $\Delta C = C_S - C_N = -\frac{2B_c^2(0)T}{\mu_0 T_c T_c} \left[1 - 3\left(\frac{T}{T_c}\right)^2\right]$
