A distillation column is initially designed to separate a mixture of toluene and xylene at around ambient temperature (say, 100°

C) and pressure (say, 1 barg). The column has 20 stainless steel valve trays and is 2 m in diameter and 14 m tall. Determine the purchased cost and the bare module cost using a CEPCI = 582.

A 78-percent efficient 12-hp pump is pumping water from a lake to a nearby pool at a rate of 1.5 ft3/s through a constant-diamet
fenix001 [56]

Answer:

irreversible head loss is 38.51 ft

mechanical power 6.55 hp

Explanation:

Given data:

Pump Power 12 hp = 8948.39 watt = 6600 lbs ft/sec

Q = 1.5 ft^3/s

Pump actually delivers P'  = \eta P = 0.78 \times 8948.39 = 6979.74 watt

Power that water gains= mgh = \rho \phi gh = r \phi h

P = 62.4 \times 1.5 \times 32 = 2995.2 lbs ft/sec

hence Power lost = 6600 - 2995.2  3604.8 lbs ft/sec = 6.55 hp

head losshl = \frac{3604.8}{r \phi} = \frac{3604.8}{62.4 \times 1.5}

hl = 38.51 ft

The vertical force P acts on the bottom of the plate having a negligible weight. Determine the shortest distance d to the edge o
Greeley [361]

Answer:

The shortest distance d to the edge of the plate is 66.67 mm

Concepts and reason

Moment of a force:

Moment of a force refers to the propensity of the force to cause rotation on the body it acts upon. The magnitude of the moment can be determined from the product of force’s magnitude and the perpendicular distance to the force.

Moment(M) = Force(F)×distance(d)

Moment of inertia ( I )

It is the product of area and the square of the moment arm for a section about a reference. It is also called as second moment of inertia.

First prepare the free body diagram of sectioned plate and apply moment equilibrium condition and also obtain area and moment of inertia of rectangular cross section. Finally, calculate the shortest distance using the formula of compressive stress (σ) in combination of axial and bending stress

Write a SELECT statement that returns these four columns:
labwork [276]

A SELECT command pulls zero or more rows from one or more database tables or views. SELECT is the most often used data manipulation language (DML) command in most applications. See the statement required below.

<h3>What is the SELECT Statement that gives the above results?</h3>

SELECT VendorName, InvoiceNumber, InvoiceDate,

InvoiceTotal - PaymentTotal - CreditTotal AS Balance

FROM Vendors JOIN Invoices

ON Vendors.VendorID = Invoices.VendorID

WHERE InvoiceTotal - PaymentTotal - CreditTotal > 0

ORDER BY VendorName;

If a law enforcement officer stops a vehicle for a traffic violation and finds a front-seat passenger 18 years of age or older n
Serggg [28]

Safety belt violation would be charged to the front seat passenger.

Answer: Option A.

<u>Explanation:</u>

Essential safety belt laws permit law implementation officials to ticket a driver or traveler for not wearing a safety belt, with no other traffic offense occurring. 11 states incorporate back seats as auxiliary implementation. Five of these are states with essential safety belt laws for front seat tenants.

In 15 of the 50 expresses, the safety belt law is viewed as an optional offense, which implies that a cop can't stop and ticket a driver for the sole offense of not wearing a safety belt. (One special case to this is Colorado, where kids not appropriately limited is an essential offense and brings an a lot bigger fine.)
