Calculate the monthly averaged daily solar radiation on a horizontal surface for Dubai, latitude=25.2048° N and longitude= 55.2708° E, for the months of January to December. Assume that the UAE standard time is referenced to Abu Dhabi: (capital city) 24° 28' N, 54° 22' E. Plot the result.

A piston-cylinder device fitted with stops as shown in the figure initially contains one kg of water at 400 kPa and 300°C. Heat is rejected from the cylinder at constant pressure until water exists in the cylinder as a saturated vapour and the piston rests on the stops. Heat rejection from the cylinder continues until the pressure is 100 kPa. Calculate the dryness fraction at the end of process.

(A) A 2.5m long steel towing bar of solid circular section diameter 50mm is expected to carry a maximum load of 300kN. The factore of safety is 4; and for the steel the UTS is 540Mnm*-2 (to the power of -2) and the modulas of elasticity is 200 GNm*-2.

(I) Calculate the actual towing capacity of the bar and state whether the proposed limit is acceptable.

(II) Determine the extension of the bar under the maximum proposed load.
