Hi, can you only help with A and B here? I am looking to get this started. Please draw a clear schematic if you think it differs from the picture in any respect.

A solar collector and storage tank, shown in Fig. 8-15a, is to be optimized to achieve minimum first cost. During the day the temperature of water in the storage vessel is elevated from 25°C (the minimum useful temperature) to tmax, as shown in Fig. 8-15b. The collector receives 260 W/m² of solar ener- gy, but there is heat loss from the collector to ambient air by convection. The convection coefficient is 2 W/(m² · K), and the average temperature differ- ence during the 10-hour day is (25 + tmax)/2 minus the ambient temperature of 10°C. The energy above the minimum useful temperature of 25°C that is to be stored in the vessel during the day is 200,000 kJ. The density of water is 1000 kg/m³, and its specific heat is 4.19 kJ/(kg · K). The cost of the solar collector in dollars is 20A, where A is the area in square meters, and the cost…

Please no written by hand solutions A 4-ton heat pump is installed. Desired flow rate is 12 USgpm. The runner and header from the Mechanical room is 110 feet in delivery and 110 feet in return. The fluid running in the system is Methanol-20%. The ground loop consists of three parallel vertical loops each 290 feet in length. The ground loop is made of 0.75" HDPE SDR 11 pipes and the runner-header is made of 1.25" HDPE SDR 11 pipes. The heatpump pressure drop is given 5.8 ft of wc for a flow of 6 gpm of water (Correction factor 20% Propylene Glycol:1.36, 20% Methanol: 1.25, 25% Ethanol: 1.32). Q: Calculate the pressure drop in the Runner-Header. Question 11 options: 9.9 ft of wc 5.8 ft of wc 7.3 ft of wc 3.8 ft of wc 13.4 ft of wc 2.9 ft of wc

### Develop the objective for a project report of a cell for the energy reuse of superheated steam within a thermoelectric power plant. The main focus is to determine the pressure drop within the system of this cell and the hydraulic compression pump contained within it. The cell contains, in all, the following equipment: Upstream: Two (tap) switching valves Two eccentric gearboxes Two pressure gauges Downstream: Two pressure gauges Two concentric magnifications A check valve (ball) A (tap) shut-off valve An expansion joint

6. Air as an ideal gas flows through the turbine and heat exchanger arrangement. Data for the two flow streams are shown on the figure. Heat transfer to the surroundings can be neglected, as can all kinetic and potential energy effects. Determine T3, in K, and the power output of the second turbine, in kW, at steady state.

Determine the coefficients of performance of the refrigeration cycle.
