1) The Bay of Fundy-Passamaquoddy area near the border between Maine and New Brunswick/Nova Scotia in Canada, is another prime site for tidal power. The basin area is 700km² and the average tidal range is 10.8 meters. Calculate the theoretical maximum power generating capability and the estimated realistic power available from this site. (SHOW your WORK)

2) A client wants you to design a roof-mounted solar water heater to supplement the energy input to their radiant floor heating system. They would like to have an indirect solar collection system similar to the one shown in Figure 11.16 of your textbook. The south-facing solar collector has a stated efficiency of 41%, and will be used to INDIRECTLY heat water in a supplemental storage tank that has a capacity of 150 Liters (~ 40 gallons). The circulating pump will operate at the rate of 20 x 10^-6 m³/sec. On a typical summer day, there are 5.6 hours of direct sunshine, which creates a 15.5°C temperature rise in the solar collector fluid for that whole time period. Assume the collector fluid is water (heat capacity of 4.184 J/g-°C). What will be the increase in temperature of the water in the storage tank?

A 2-Kg mixture of 20% N2 , 30% O2 and 50% CO2 by mass is heated to 500 K with constant volume. Find The final pressure and the total heat transfer needed.

field engineering is a stressful job, why would you choose it be a field engineering?

how do I answer this interview question?

In other words, how do I show that I am able to afford stress

please give an example

A rigid tank of volume 0.75 m3 is initially evacuated. A hole develops in the wall, and air from the surroundings at 1 bar, 30°C flows in until the pressure in the tank reaches 1 bar. Heat transfer between the contents of the tank and the surroundings is negligible. Determine the final temperature in the tank, in °C.

2) Explain the meaning of 4 different alloy codes by giving the composition and temper condition. State the applications in which these alloys can be used and explain the reasons why these alloys should be used in these specific applications.

A 2-m-high, 4-m-wide rectangular advertisement panel is attached to a 4-m-wide, 0.15 m-high rectangular concrete block (density = 2300 kg/m³) by two 5-cm-diameter, 4-m-high (exposed part) poles, as shown in the figure. If the sign is to withstand 150 km/h winds from any direction, determine (a) the maximum drag force on the panel, (b) the drag force acting on the poles, and (c) the minimum length L of the concrete block for the panel to resist the winds. Take the density of the air to be 1.3 kg/m³.

Air at 30 C flows at 10 m/s across an in-line tube bank consist of 5 rows with 10 tubes per row. The diameter of the tube is 5 cm and the tube pitch is 13 cm. Water flowing in tube maintains the tube surface temperature at 80C find the following:

a) the air temperature at the outlet of the tube

b) the convective heat transfere per unit length per tube to the air

( it is heat transfer problem )

A steam power plant operates with a boiler that is heated from a heat source at 457 °C and produces 450 ton/hr. of steam. The steam leaves the boiler at 425 °C and 4 MPa. The steam reaches a turbine at 375 °C and 3 MPa and leaves it at 50 kPa with 4% liquid water. This mixture is flown into a condenser that rejects the heat into a river at 17 °C. Water leaves the condenser at 50 kPa and 50 °C and pumped by a pump operating at 10 kJ/kg. The water leaves the pump at 4 MPa.
