This is a complete question I am stuck in. Kindly answer as soon as possible.
Heated air at 1 atm and 100°F is to be transported in a 900-ft-long circular section plastic duct at a rate of 1.4 lb/s. I want to determine the head loss and pumping power at the three diameter values in the table below. Complete the table to help me choose a wise diameter. Why would a good design not only focus on minimizing the pumping power? Diameter Head loss, hi Pumping power, W Reynolds number, Re n.d. f n.d. (in) ft hp 8 12 16

Water at a flow rate of 1kg/s is flowing in a pipe of internal diameter 5 cm. If the inside pipe surface temperature is 90°C and mean bulk water temperature is 50°C, compute the convective heat-transfer coefficient. Estimate the convective heat.
Liquid ammonia is transported from a production plant to a processing center via a 0.6-m diameter pipeline at a mass flow rate of 0.15 kg/s. Surface temperature of the pipe is maintained 0°C by using a cooling jacket with ice-cold water. Ammonia enters the pipeline at -17°C and exits at -3°C. Assume the flow is both hydrodynamically and thermally fully developed in the pipe. What is the length of the pipe? 185.7m
Air at p= 1 atm enters a thin-walled (D= 5-mm diameter) long tube (L= 2 m) at an inlet temperature of Tm,i= 100°C. A constant heat flux is applied to the air from the tube surface. The air mass flow rate is m˙ = 130 × 10-6 kg/s. If the tube surface temperature at the exit is Ts,o=160°C, determine the heat rate entering the tube, in W. Evaluate properties at T=400 K.
- EXAMPLE 8-1 Laminar Flow in Horizontal and Inclined Pipes Consider the fully developed flow of glycerin at 40°C through a 70-m-long, 4-cm-diameter, horizontal, circular pipe. If the flow velocity at the centerline is measured to be 6 m/s, determine the velocity profile and the pressure dif- ference across this 70-m-long section of the pipe, and the useful pumping power required to maintain this flow. For the same useful pumping power input, determine the percent increase of the flow rate if the pipe is inclined 15° downward and the percent decrease if it is inclined 15° upward. The pump is located outside this pipe section.
