A Air at a temperature of 134°C and atmospheric pressure flows with a velocity of 7 m/s over a smooth 5 m long and 1 m wide cast iron plate. Under steady-state conditions, the air-side

surface temperature of the plates is at 120°C. Under the described conditions, determine the

overall heat transfer rate through the plate.

B-If the flat plate in (A) is replaced with a cylinder with the same surface area (heat transfer

area) and the cylinder's length is the same as the width of the plate (1.0 m), what would be the

heat transfer rate for cross air flow over the outside surface of the cylinder?

C. If the flat plate in (A) is replaced with a sphere with the same surface area (heat transfer area),

what would be the heat transfer rate for cross air flow over the outside surface of the sphere?

D- Based on your results, discuss which surface configuration is more effective for heat

dissipation and why.

Apiece of metal with a length of 1.42 cm was measured using four different instruments. which of the following measurements is the most accurate?

What is the relationship between wind and ocean waves? question 17 options: wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves. wind moving at higher speeds will transfer energy over a larger part of the ocean water, resulting in waves with a shorter wavelength. winds moving at higher speeds with cause water to move forward at faster rates, causing larger ocean waves. winds moving at higher speeds will affect deeper water, resulting in waves that move at a faster rate. how do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
