- CASE: Answer clearly and concisely. how does your computations go when for example all needed info are derived as usual and THE PIPE SIZE IS UNKNOWN.Water flows at 5m/s is passed through a tube of 2.5 cm diameter, it is found to be heated from 20degC to 60degC. The heating is achieved by condensing steam on the surface of the tube and subsequently the surface temperature of the tube is maintained at 90degC. Water properties are as follows: density=995kg/m3, kinematic viscosity=.657x10-6 m2/s, Pr=4.43, k=.628W/mK, cp=4178J/kgK. Determine the Reynolds number Round your answer to 2 decimal places. What is the thermal coefficient Round your answer to 2 decimal places. what is the heat absorbed by the water? Round your answer to 2 decimal places.In a gas manufacturing plants, they presented a horizontal tube in which a gas assumed to be ideal is flowing steadily. It was identified that no heat and work interaction was done. Also, there is a significant changes in the pipe diameter as well as velocity. If in case we select N2 as the flowing gas at 761.67 R at a velocity of 5.6 m/h, Calculate the temperature where the velocity us 180 km/h? Assume cp=7/2 R.
- An oil is being pumped inside a 10.0 mm diameter pipe. The oil’s density is 855 kg/m3 and its viscosity is 2.1×10-2Pa·s. It is required that the flow remain in the laminar regime and thus the Reynolds number cannot exceed 2100.What is the maximum velocity in the pipe?plzzz i neeed the answer right nowwww What is the air pressure (kpa) in a car tier? The pipe pressure is measured to be 20 kpa. For layers of oils, given that S1=1.0, S2=0.8, and S3=0.17.Draw a diagram to explain what it means: flow separation, the mechanism by which fluid separation occurs, and give examples of how to delay separation and its effect on resistance

Water properties are as follows: density=995kg/m3, kinematic viscosity=.657x10-6 m2/s, Pr=4.43, k=.628W/mK, cp=4178J/kgK. a) Determine the Reynolds number b) What is the thermal coefficient on question number c) what is the heat absorbed by the water?Calculate the capillary effect in mm in a glass tube of 6 mm diameter when immersed in (i) water, and (ii) mercury, both liquids being at 20°C. Assume σ to be 73 × 10−3 N/m for water and 0.51 N/m for mercury. The contact angles for water and mercury are zero and 130°, respectively.Merrill et al. (1965) in a series of classic experiments studied the flow of blood in capillary tubes of various diameters. The blood had a hematocrit of 39.3 and the temperature was 20°C. They measured the pressure drop as a function of the flow rate for five tube diameters ranging from 288 to 850 μm. When they expressed the measured pressure drops in terms of the wall shear stress, and the volumetric flow rates in terms of the reduced average velocity, all of the data for the various tube sizes formed, within the experimental accuracy, a single line as predicted by the Rabinowitsch equation expressed in terms of reduced average velocity. From their results they provide the following values of the Casson parameters at 20°C: τy = 0.0289 dynes cm−2 and s = 0.229 (dynes s cm−2)1/2. Using these values for τy and s, show that the equation below for reduced average velocity provides an excellent fit to their data summarized in the following table. (Wall shear stress) τw , dynes cm-2…
