Engineers are the reason healthcare has improved so dramatically throughout the years. The advancements in medical technology are down to the work conducted by engineers as well as the creation of devices that help to save lives and improve the quality of life for others. New developments are being created by engineers constantly, for example, the Crossrail project in London is creating a new transport system throughout the South East to create shorter journey times and easier connections. The existing transport system wouldn’t be where it is today without engineers.
Answer:
domestic, public, commercial, and industrial uses.
Answer:
a) C_v = 1.005 KJ/kgK
b) C_v = 1005.000 J/kgC
c) C_v = 0.240 kcal/kgC
d) C_v = 0.240 Btu/lbmF
Explanation:
Given:
- constant-pressure specific heat C_v = 1.005 KJ/kgC
Find C_v in units of:
a) kJ/kg·K
b) J/g·°C
c) kcal/ kg·°C
d) Btu/lbm·°F
Solution:
a) C_v is Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass. Usually, it's the heat in Joules needed to raise the temperature of 1 gram of sample 1 Kelvin or 1 degree Celsius. Hence,
C_v = 1.005 KJ/kgK
b)
C_v = 1.005 KJ/kgC * ( 1000 J / KJ)
C_v = 1005.000 J/kgC
c)
C_v = 1.005 KJ/kgC * ( 0.239006 kcal / KJ)
C_v = 0.240 kcal/kgC
d)
C_v = 1.005 KJ/kgC * ( 0.947817 Btu / KJ) * ( kg / 2.205 lbm)*(Δ1 C / Δ1.8 F)
C_v = 0.240 Btu/lbmF

Answer:
d = 2.711
H = 4.06 inch
Explanation:
Given Data:
length = 1.5 times of diameter of cylinder
square plate side = 12 inch, thickness = 1.1 inch
mold constant = 13.0 min/in^2
Casting volume

t is thickness and L is length
substitute t = 1.1 inch, L =12 inch

casting area


A = 340.8 in^2
Ratio between casting volume and area

Total solidification time TST using chvorinov rule
![TST = Cm [\frac{V}{A}]^2](https://tex.z-dn.net/?f=TST%20%3D%20Cm%20%5B%5Cfrac%7BV%7D%7BA%7D%5D%5E2)
Cm is mold constant
