Study Notes
Thermodynamic State of a Fluid
- Properties such as temperature, pressure, and density describe the thermodynamic state of a fluid.
Viscosity
- Viscosity measures the resistance of a fluid to shear stress, indicating its thickness or flowability.
Simple Shear
- In an example of simple shear between two plates, the upper plate moves at a steady speed.
Boiling Point of Water
- At an elevation of 10,000 ft, water boils at a lower temperature due to lower atmospheric pressure.
- At 10,000 ft, water boils at a temperature lower than 212°F (100°C).
- At the same elevation, the vapor pressure of water is lower than the atmospheric pressure.
Pressure Cooker
- A pressure cooker increases the boiling point of water by increasing the pressure inside the cooker.
Inventory Control
- A primary objective of inventory control is to minimize waste and optimize the use of resources.
- Inventory control aims to reduce waste by ensuring the right materials are available at the right time.
Just-in-Time (JIT) Approach
- The goal of the JIT approach is to minimize inventory levels by ordering and receiving inventory just in time for production.
Forecasting Material Needs
- The Material Requirements Planning (MRP) method helps to forecast the material needs of the production process.
Optimal Order Quantity
- The Economic Order Quantity (EOQ) formula determines the optimal order quantity for a product, balancing the benefits of holding larger inventories against the costs of ordering more frequently.
Benefits of Inventory Control
- Implementing an inventory control system leads to reduced waste, optimized resource use, and improved supply chain management.
Challenges in Inventory Control
- One challenge associated with inventory control is managing a diverse range of products.
- Effective inventory control helps businesses with supply chain management.
