Explanation The following figure shows the p - v diagram for Otto cycle. Figure-(1) In Figure-(1), the Y -axis shows the pressure, while the X -axis shows the specific volume for Otto cycle. The working fluid compressed isentropically from state 1 to state 2, heat addition takes place between state 2 to state 3 at constant volume, isentropic expansion takes place from state 3 to state 4 and constant volume heat rejection takes from state 4 to state 1. The following figure shows the p - v diagram for Diesel cycle. Figure-(2) In Figure-(2), the Y -axis shows the pressure, while the X -axis shows the specific volume for Diesel cycle. The working fluid compress isentropically from state 1 to state 2, heat addition takes place between state 2 to state 3 at constant pressure, isentropic expansion takes place from state 3 to state 4 and constant volume heat rejection takes from state 4 to state 1. The following figure shows the p - v diagram for Dual cycle

First monthly exam Gas dynamics Third stage Q1/Water at 15° C flow through a 300 mm diameter riveted steel pipe, E-3 mm with a head loss of 6 m in 300 m length. Determine the flow rate in pipe. Use moody chart. Q2/ Assume a car's exhaust system can be approximated as 14 ft long and 0.125 ft-diameter cast-iron pipe ( = 0.00085 ft) with the equivalent of (6) regular 90° flanged elbows (KL = 0.3) and a muffler. The muffler acts as a resistor with a loss coefficient of KL= 8.5. Determine the pressure at the beginning of the exhaust system (pl) if the flowrate is 0.10 cfs, and the exhaust has the same properties as air.(p = 1.74 × 10-3 slug/ft³, u= 4.7 x 10-7 lb.s/ft²) Use moody chart (1) MIDAS Kel=0.3 Q3/Liquid ammonia at -20°C is flowing through a 30 m long section of a 5 mm diameter copper tube(e = 1.5 × 10-6 m) at a rate of 0.15 kg/s.
