(a) Figure Q2a shows a Photovoltaic/Thermal (PV/T) system that consists of a monocrystalline PV module and a spiral-shaped thermal collector configuration. The PV/T system installed at Sohar University renewable energy lab. The cooling fluid is Aluminum Oxide nanofluid. The PV module produces 84 W of power when exposed to an irradiance of 950 W/m², and its area is the same as the absorber, which is 0.85 m². The water flowrate is 0.017 kg/s, and its specific heat is 4200 J/kg°C. (i) Calculate the electrical efficiency of the PV/T. [4 Marks] (ii) Determine the thermal efficiency of the PV/T if the difference between the outlet and inlet nanofluid temperature is 7 °C. [5 Marks] (iii) Calculate the total efficiency of the PV/T. [2 Marks] Flow Meter PV Collector PV/T Collector Hot to Fixtures Tout Cold Supply In T.in Expansion Tank Tempering Valve Temperature Gauge Valve Storage Tank Temperature Gauge Nanofluid Tank Pump Temperatur Gauge Valve: Tank Outlet

Gilberto’s car was relatively unharmed by the collision but required 1,200 in minor repairs. Juanita’s car was destroyed, making Gilberto liable for paying the $10,400 replacement value. Juanita’s car was pushed up onto a nearby sidewalk on impact, destroying a nearby lawn and causing additional damage to a parked car. This damage totaled $8,693. Gilberto’s liability coverage also will reimburse him for up to $50,000 worth of property damage. Therefore, he is responsible for paying$0 out-of-pocket in property liability damages. Which of the following is true regarding the damage to his own car?

Compute the determinant by cofactor expansion. At each step, choose a row or column that involves the least amount of computation. $\begin{vmatrix} 4 & 2 & 3 & 4 & 0 \\ 4 & 0 & -3 & 1 & 0 \\ 7 & -9 & 6 & 2 & 1 \\ 4 & 0 & 0 & 0 & 0 \\ 8 & 3 & 4 & 2 & 0 \end{vmatrix} = \square$ (Simplify your answer.)
