Unformatted text preview: ∂vol v /∂p along the saturated vapor line. Is it a reasonable engineering assumption to neglect this eﬀect in this system? 4. Now, the pipe is heated at a constant rate to produce a linear quality proﬁle ( i.e., x = 0 at the inlet, 1 at the outlet, 0.5 halfway up [5 m], etc.) Assume that the two-phase friction factor is equal to the liquid-only friction factor and that the properties of steam and water can be estimated at their saturated states at 7 MPa throughout the pipe. Neglect vapor compressibility and analytically integrate Equation 11-78 to compute the total pressure loss from saturated liquid to saturated vapor. 5. Is assuming constant properties is a good engineering simpliﬁcation for this system? In your answer, consider how much eﬀort accounting for variations in properties with pressure would be....
