1. An air-standard Diesel cycle has an input data described in the table below: Parameter Value Compression ratio, 19 90 mm r Stroke Number of cylinders 6 Cylinder diameter Initial pressure, pi 105 mm 1 bar Parameter Initial temperature, 23C T₁ Number of cycles per minute Gas constant, R Ср Value 3000 cycles/minute 8.314/28.47 kJ/kg*K 1.105 kJ/kg*K Cy 0.821 kJ/kg*K rc 2.1 The number of cylinders you need only for computing the net power production for the whole engine. For an ideal gas equation (If you will use it) use Pa for pressure and K for Temperature! a) Draw the P-9 diagram showing all stages of the process b) Volume of a gas at BDC (Bottom Dead Center) V₁=? [m³] To answer to this question you may have to compute the volume of the cylinder with known diameter and stroke c.) Volume of a gas at TDC (Top Dead Center) V2=? [m³] d.) Specific volume at the initial conditions ₁=? [m³/kg] You can use ideal gas equation. The R=8.314/28.97 kJ/kg*K. Please, convert to JOULES/kg*K! Otherwise, your specific volume will be very small. Or use the air properties calculator.
