Need detailed solution. 4 decimal places. Oil with a specific gravity of 0.82 is flowing in a pipe under the condition below. If the total head loss from point 1 to point 2 is 3 ft, find the pressure at point 2 in psi. *cfs = cubic ft per sec

1. Water at 60 °F flows through a 6-in. schedule 40 pipe (Dri= 6.065 in.), through a reducer, and then through a 4-in. schedule 40 pipe ( Dro = 4.026 in) at a rate of 80 gal/min. The pressure is 40 psig at the reducer inlet and 34 psig at the reducer outlet. Determine the force of the water on the reducer. Note: A reference other than this textbook will readily provide the actual inside diameter of the schedule 40 pipes you will need to answer this question. V2 reducer 4 in. pipe 6 in. pipe

Hi, I unfortunately cant see the full explanation, is there any way the writing could be condensed to show all of it on the screen?

Please type answer no write by hend.

Can you please solve correctly

PLEASE ANSWER QUESTION # 2 ONLY, DISREGARD THE OTHER PROBLEMS GIVEN. SHOW COMPLETE SOLUTION. THANK YOU.   Intravenous infusions usually are driven by gravity by hanging the fluid bottle at sufficient height to counteract the blood pressure in the vein and to force the fluid into the body (fig. below). The higher the bottle is raised, the higher the flow rate of the fluid will be.   An 8 ft diameter by 16 ft height vertical tank is receiving water (? = 62.5 lb/ft3) at the rate of 295 gal/min and discharging through a 4-in ID line with a constant speed of 6 fps. At a given instant, the tank is half full.     QUESTION #1: the mass change in the tank (sample answer: 20,287.65 lb. round off to 2 decimal place   QUESTION #2: the water level in the tank 15 min. later (sample answer: 20,287.65 ft  round off to 2 decimal place   QUESTION #3: the volume change in the tank (sample answer: 20,287.65 cu ft  round off to 2 decimal place

i) The Alaska pipeline conveys crude oil 800 miles across the state of Alaska from Prudhoe Bay to Valdez. The inside diameter of the pipeline is 48 inches. The pipe wall thickness is of ½ inch of commercial steel and is insulated by an additional ½ inch thickness of rigid foam. Considering the properties of crude oil: a) Calculate the Reynolds number of the oil flow.  b) Find the pressure loss per foot length of the pipeline. You may neglect minor losses for this problem.  ii) For nominal conditions of -50°F outside air temperature and the cross-wind speed of 12mph c) First find the inside convective heat transfer coefficient (hint: you need to use the second Petukhov equation). d) Next find the external convective heat transfer coefficient (hint: you need to use Churchill & Bernstein; assume a film temperature of -25°F for air properties).  e) Lastly, neglecting radiation, calculate the heat loss per foot of the pipeline in Btu/hr. iii)The distance from the last pumping station to…

QUESTION 4 The figure below shows a fluid flow system that is designed to pump water at 20 °C from a lower vented reservoir to an elevated vented tank. Note that the drawing is not to scale as the dimensions of the reservoirs are very large relative to those of the piping system. The suction line entering the pump is specified as 20 m of 3½" schedule 40 commercial steel pipe; the discharge line from the pump is 180 m of 2%" schedule 40 commercial steel pipe. 15 m 3 m 31/2-in Schedule 40 steel pipe Fully open gate valve 21/2-in Schedule 40 steel pipe Flanged regular 90⁰ elbows Pump Flow Swing-type check valve valve Butterfly (K butterfly = 0.8) a. Starting from the Bernoulli equation (in 'head' form) for the situation where the liquid levels in the two reservoirs are reference points 1 and 2, derive the correct equation for pump head Hpump (m) in terms of volumetric flow rate Q (m³/s) and other process variables (e.g. z, f, L, D, K). b. Using Excel (or another suitable program), create…

Sulfuric acid with a density of 1980 kg/m³ and a viscosity of 26.7 cP is flowing in a 35 mm diameter pipe.

QUESTION 1 of From pump 1.0 m a. Using a vertical bar chart, plot the pressure drop (i.e. P₁-P₂) for these eight nominal pipe sizes: 3/4", 1", 1- 1/4", 1-1/2", 2", 2-1/2", 3", 4", 6", and 8" 1.5 m Given the following conditions: Carbon tetrachloride at 20 °C is flowing through the piping system at a volumetric flow rate of 0.2 m³/min Total length of piping = 50 m Piping to be used is schedule 40 carbon steel pipe with an absolute roughness = 0.05 mm All 45° and 90° elbows have 'threaded regular' geometry Use the nominal pipe dimensions (3/4", 1", etc) for the x-axis labels but be sure to use the actual internal pipe diameters (given in document titled 'Table D1 in Janna textbook') in your calculations. HINT: Using a logarithmic scale on the y-axis scale will allow you to better compare the entire range of values. b. Re-do plot from part a, but now include the total cost (in USD) of the piping (you can ignore the costs associated with the fittings) on a secondary y-axis. For the piping…
