Consider the current pulse i(t) shown in Figure a below. The current begins at zero, becomes 10.0 A between t = 0 and t = 200 µs, and then is zero once again. This pulse is applied to the input of the partial circuit shown in Figure b below. (Let R = 200 ? and L = 14.0 mH.) Determine the current in the inductor as a function of time. (Use the following variable as necessary: t. If the current in a range is always zero, enter 0. Assume i is in amperes and t is in seconds. Do not include units in your answer.) for t ? 0 µs i = 0 for 0 ? t ? 200 µs i = for t ? 200 µs i =

Texts: Help me to answer this question, step by step using the table of properties you have, capture the heat from the geothermal fluid. Your proposed layout is sketched in Fig.1 Site Office Heating demand = 500 kW saturated liquid P3 = 20 bar Qout Pz = 20 bar Condenser mwf = ? Binary Cycle plant Expansion Valve n = 0.75 Compressor P4 = 0.6 bar Evaporator P = 0.6 bar saturated vapor Qir ngeo = 18.2 kg/s Tineo = 50°C Tgut = Geothermal Reservoir Figure 1. Schematic of proposed heat pump installation at the site The heating demand of the building is 500 kW. You decide that Ammonia (NH3) is the most suitable refrigerant to use as the working fluid in the heat pump. The compressor is designed with an isentropic efficiency of 75%, whereas the condenser is assumed to be 100% efficient. Calculate the mass flow rate of the Ammonia working fluid, mwf, required to meet the heating demand of the building.
Test the claim about the difference between two population means $\mu_1$ and $\mu_2$ at the level of significance $\alpha$. Assume the samples are random and independent, and the populations are normally distributed. Claim: $\mu_1 \le \mu_2$; $\alpha = 0.05$. Assume $\sigma_1^2 \ne \sigma_2^2$ Sample statistics: $\bar{x}_1 = 2400$, $s_1 = 170$, $n_1 = 15$ and $\bar{x}_2 = 2298$, $s_2 = 53$, $n_2 = 9$ Identify the null and alternative hypotheses. Choose the correct answer below. A. $H_0: \mu_1 = \mu_2$ $H_a: \mu_1 \ne \mu_2$ C. $H_0: \mu_1 > \mu_2$ $H_a: \mu_1 \le \mu_2$ E. $H_0: \mu_1 < \mu_2$ $H_a: \mu_1 \ge \mu_2$ B. $H_0: \mu_1 \ne \mu_2$ $H_a: \mu_1 = \mu_2$ D. $H_0: \mu_1 \ge \mu_2$ $H_a: \mu_1 < \mu_2$ F. $H_0: \mu_1 \le \mu_2$ $H_a: \mu_1 > \mu_2$
