Question

An idealized radial turbine is shown in Fig. P11.87. The absolute flow enters at $30^{\circ}$ and leaves radially inward. The flow rate is $3.5 \mathrm{m}^{3} / \mathrm{s}$ of water at $20^{\circ} \mathrm{C}$. The blade thickness is constant at $10 \mathrm{cm} .$ Compute the theoretical power developed.

Water drives a waterwheel (or turbine) of radius $R = 3.0 m$ as shown in Fig. 8-66. The water enters at a speed $\upsilon_1 = 7.0 m/s$ and exits from the waterwheel at a speed $\upsilon_2 = 3.8 m/s$. $(a)$ If 85 kg of water passes through per second, what is the rate at which the water delivers angular momentum to the waterwheel? $(b)$ What is the torque the water applies to the waterwheel? $(c)$ If the water causes the waterwheel to make one revolution every 5.5 s, how much power is delivered to the wheel?

A firm has outstanding a bond with a 5-year maturity and maturity value of $\$ 50$ convertible into 10 shares. There are also 20 shares outstanding. What is the price of the warrant? The share price? Suppose you were to compute the value of the convertible as a risk-free bond plus an option, valued using the Black-Scholes formula and the share price you computed. How accurate is this?

Points _ Solve the non-linear initial value problem t(x' (t))2 + 2tx' (t) r(t) 0 with =(1) = -1, for t 2 1, by making the substitution c(t) y(t) - t. You will get full credit as long as you find at least one solution that solves this IVP for all t 2 1 and show your work no need to worry if there are other solutions as well:(To be clear, this means the ODE is t(x')2 + 2tx' x = 0 where € is a function of t.)
