Question 109
Open questionXE-ENAT2 marksNeeds review
A rigid and impermeable tank has only moist air with a specific humidity of 0.025 kgwater-vapor/kgdry-air at 30 °C and 101 kPa. The air is heated to 90 °C. Assume moist air to behave as an ideal gas. The relative humidity (in %) of the heated air is ____________ (rounded off to two decimal places).
Saturation pressure of water at 30 °C is 4.25 kPa and at 90 °C is 70.18 kPa.

Open questionXE-FMCQ1 markNeeds review
The stress-strain profiles in the figure were obtained following longitudinal tensile loading for a brittle polymer, glass fibre, and a composite lamina consisting of unidirectional continuous glass fibres and the polymer matrix. Assume that the matrix is free of voids, there is perfect bonding between glass fibres and the matrix, and there are no residual stresses in the composite lamina.
Identify the correct stress-strain profile for the polymer matrix, glass fibre, and their composite lamina from the above figure.
