Question

How would you solve this

. 3: Using dimensional analysis and showing all work, convert the following:
(a) 248 pounds to newtons and kilonewtons
(b) 8,478 lb/in?(psi) to megapascals (MPa)
(c) 14 yd² to mm² and m2
(d) 3.5 kips/ft. to kN/m

Expert Solution

Step 1

Given

Pounds = 248

Solution

1 Pound = 4.4482 N

Therefore,

248 Pounds = 248 x 4.4482 N

= 1103.15 N

1 Pound = 0.0044482 kN

248 Pounds = 248 x 0.0044482 kN

= 1.10315 kN

Dimensional analysis is to be used to correlate data on bubble size with the properties of the liquid when gas bubbles are formed by a gas issuing from a small orifice below the liquid surface. Assume that the significant variables are bubble diameter D, orifice diameter d, liquid density rho, surface tension sigma (in N/m), liquid viscosity mu, and g. Select d, rho, and g as the core variables.
