Complete the following unit conversions, if possible. Show your work.a. 3052 mm = _______________ inb. 25.0 psi = _______________ kPac. 552 cm3 = _______________ gald. 95.0 mile2 = ______________ km2e. 192 BTU/hr = ______________ Wf. 2225 Pa = _______________ BTU

Answer 1

(a). Given value is,

$\begin{gathered} d=3052\text{ mm} \\ d=\frac{3052}{25.4} \\ d=120.2\text{ in} \end{gathered}$

Thus, the value from mm to in is 120.2 in.

(b). Given value is,

$\begin{gathered} P=25\text{psi} \\ P=25\times6895 \\ P=172369\text{ Pa} \\ P=172.4\times10^3\text{ Pa} \\ P=172.4\text{ kPa} \end{gathered}$

Thus, the value from psi to kPa is 172.4 kPa.

(c). Given value is,

$\begin{gathered} V=552cm^3 \\ V=\frac{552}{3785} \\ V=0.146\text{ gal} \end{gathered}$

Thus, the value is 0.146 gal.

(d). Given value is,

$\begin{gathered} A=95mile^2 \\ A=95\times2.59 \\ A=246.05km^2 \end{gathered}$

Thus, the value is 246.05 km squared.

(e). Given value is,

$\begin{gathered} P=192BTUhr^{-1} \\ P=\frac{192}{3.41} \\ P=56.3\text{ W} \end{gathered}$

Thus, the value is 56.3 W.

(f). The given value is,

$\begin{gathered} P=\text{ 2225 Pa} \\ P=2225\times0.000948 \\ P=2.11\text{ BTU} \end{gathered}$

Thus, the value is 2.11 BTU.
