Question
Chapter 5, Problem 5.11P
Interpretation Introduction
Interpretation:
Pipe dimension, flow velocity, pressure drop is to be determined.
Concept Introduction:
Bernoulli’s theorem states that the summation of kinetic energy, potential energy, and head loss for flow through a pipe is constant. However, when friction is considered, this value does not remain constant. Instead, it decreases in the direction of flow due to

You are considering designing a surgetank to place upstream of the reactor and then installing a pump on the line between that surge tank and thereactor. A surge tank is one with a weir inside it, which is a partial wall separating the tank volume into twoconnected sections allowing for flow under the weir between the two sections. The variable inlet mass flow,wi(t) flows into volume 1 and then flows due to hydrostatic pressure at a mass flow rate of w1(t) into volume 2.The weir causes a flow resistance, R1, such that w1 = (h1-h2)/R1. Fluid is then pumped out of volume 2 at thedesired constant mass flow rate of w2. Make a summary table of the three transfer functions written in standard form and their keyparameters (gains, time constants) in terms of the physical system parameters (A1, A2, , A, R…).

- Hydrogen (H₂) is considered a clean energy carrier. For its use as a fuel, hydrogen is stored at 5 bar insidea cylindrical tank made of nickel (Ni) with 7 cm inner diameter, 1.2 mm thickness, and the length of L. Thetank is maintained at 358 K. Unfortunately, a small amount of hydrogen diffuses out of the tank, slowlydepleting its contents. You may assume that the hydrogen pressure outside the tank is essentially zero andconvective resistance inside and outside of the cylinder is negligible.• Solubility of H2 in Ni at 358 K = 0.00901 kmol/m3·bar• DH2, Ni at 358 K = 1.2 x 10-12 m2/sCalculate the maximum length of the nickel tank wall to ensure that the hydrogen loss does not exceed0.01 kg per year.arrow_forwardYou just took out a cold soda can (at 1 oC) from the refrigerator.

The fluidized bed includes bubbles and dense phase. □ The dense phase can be simulated using a CSTR The fluidized bed bubbles contain catalyst particles and can be simulated as a DSTR (batch). □ The jets contain particles and can be simulated with a PFR. The influence of the freeboard has to be considered using a PFR model. The available catalytic reaction rate model is r (moles/gcat.s)= -k CA b) Same than on a) under unsteady state conditions, using an absorbable and reactive tracer.
