Air enters a 4-cm-square galvanized steel duct with p0 =150 kPa, T0 = 400K, and V1 = 120 m/s. (Note: = 2.2 105N s/m2).(a) Compute the maximum possible duct length for these conditions.(b) If the actual duct length is 0.75 times the maximum value,calculate the mass flow rate, the exit pressure, and the stagnationpressure.(c) If the actual duct length is 1.3 times the maximum value forthe stated conditions, compute the new mass flow rate and inletvelocity. Assume a low back pressure and use the same value of fas used in the maximum possible duct length case.
Chapter 3: Transport Layer 3.1 Intro and Transport-Layer Services A transport-layer protocol provides for logical communication between application processes running on different hosts Transport protocol run on end systems o THey break application layer messages into segments and pass those onto the network layer, then on the way back they receive these segments and assemble them into messages for the app layer TCP and UDP are transport-layer protocols
