Question in the picture
smooth pipe: Total length, L Diameter, d -25 mm 4 m tank water (pa 1,000 kg/m3, μ 0.001 kg/ms) flows from a very large tank (that is open to atmosphere) through an L 4 m total length of smooth pipe of d = 25 mm diameter at a bulk velocity of 6 m/s. The water then exits the pipe at 3 m above ground as a free jet. The pipe network contains a gate valve (V),...

Exercise 1.16 An insulated district heating pipe with a total diameter d = 0.4 m is laid in the ground at a depth of h = 1.2 m. For a long cold period with an average ground surface temperature of 0°C and a temperature at the outer edge of the pipe insulation of 20°C, the heat loss per 1km of steam pipe must be calculated. The thermal conductivity of the soil should be assumed to be 0.6 W/mk

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...

Question The pressure drop Ap, along a straight pipe of diameter D has been experimentally studied, and it is observed that for laminar flow of a given fluid and pipe, the pressure drop varies directly with the distance I, between pressure taps. Assume that Ap is a function of D and I, the velocity V, and the fluid viscosity H. Use dimensional analysis to deduce how pressure drop varies with pipe diameter.
