Q7 An engine having a compression ratio of (15:1) operates on the ideal Dual
combustion cycle. At the beginning of compression the air in the cylinder is at
(0.986 bar) and (21 °C). After compression the heat energy supplied at constant
volume increases the temperature to (1100 °C), and the heat energy supplied at
constant pressure takes place over (4%) of the stroke. Calculate the maximum
pressure, the maximum temperature and the cycle efficiency.

The membrane has pores equivalent in size to a spherical molecule with a molecular weight of 100,000, a porosity of 80%, and a tortuosity of 2.5. On the feed side of the membrane, we have a solution containing a protein at a concentration of 8 g L-1 with these properties: a = 3 nm and DAB = 6.0 × 10-7 cm² s¹. The solution viscosity is 1 cP. The hydrodynamic pressure on the protein side of the membrane is 20 pounds per square inch (psi) higher than on the filtrate side of the membrane. Assume that the hydrodynamic pressure difference is much larger than the osmotic pressure difference (advection >> diffusion). Determine the convective flow rate of the solution across the membrane.arrow_forward1. Calculate the filtration flow rate (cm³ s¹) of a pure fluid across a 100 cm² membrane.
